(17) FIG. 1 is a diagram showing a configuration of a spectroscopic analysis device according to an embodiment of the present invention. As shown in FIG. 1, the spectroscopic analysis device 300 includes a spectroscopic analysis control device 100 and a spectrophotometer 200 for performing spectroscopic measurement. In FIG. 1, the hardware configuration of the spectroscopic analysis device 300 is mainly shown.

The CPU 110, the RAM 120, the ROM 130, the storage device 140, the operation unit 150, the display unit 160, and the input/output I/F 170 are connected to a bus 180.

(19) The RAM 120 is used as a workspace of the CPU 110. A system program is stored in the ROM 130. The storage device 140 includes a storage medium, such as, e.g., a hard disk and a solid-state memory, and stores a spectroscopic analysis control program. The CPU 110 executes a spectroscopic analysis control program stored in the storage device 140 on the RAM 120, thereby performing the spectroscopic analysis control processing which will be described later.

(20) The operation unit 150 includes an input device, such as, e.g., a keyboard and a mouse. The display unit 160 includes a display device such as a liquid crystal display device. The operation unit 150 and the display unit 160 may be configured by a touch panel. The display unit 160 sequentially displays a parameter setting screen for receiving a plurality of parameters required to quantify a concentration of a sample. The user can specify a plurality of parameters on the parameter setting screen of the display unit 160 by using the operation unit 150. The input/output I/F 170 is connected to the spectrophotometer 200.

(21) The spectrophotometer 200 includes a light emitting unit 210, a lens 220, a sample stage 230, a spatial filter 240, a spectroscopic element 250, and a light receiving unit 260. The light emitting unit 210 includes a plurality of light sources, such as, e.g., a deuterium lamp and a halogen lamp, and emits light having various wavelengths based on the control by the spectroscopic analysis control device 100.

(22) A sample 1 is attached to the sample stage 230. Here, the spectroscopic analysis device 300 includes a sample cell 310 as an accessory device, and in cases where the sample 1 is a liquid or a gas, the sample 1 is attached to the sample stage 230 in a state in which the sample is injected into the sample cell 310. On the other hand, in cases where the sample 1 is a solid, the sample 1 is directly attached to the sample stage 230. In the following description, the sample 1 in which the concentration is known is referred to as a standard sample, and the sample 1 in which the concentration is unknown is referred to as an unknown sample.

(23) The light emitted from the light emitting unit 210 is condensed by the lens 220 and irradiated onto the sample 1 attached to the sample stage 230. The light irradiated to the sample stage 230 is guided through the opening (pinhole) of the spatial filter 240 to the spectroscopic element 250. The spectroscopic element 250 is, for example, a reflective concave diffraction grating. The light guided to the spectroscopic element 250 is spatially separated for each wavelength, and is received by the light receiving unit 260.

(24) The light receiving unit 260 is a line sensor in which a plurality of light receiving elements is arranged one-dimensionally and a plurality of light separated for each wavelength is respectively received by a plurality of light receiving elements based on the control by the spectroscopic analysis control device 100. Further, the light receiving unit 260 outputs an electric signal (hereinafter referred to as “light receiving signal”) corresponding to the amount of light received in each pixel to the spectroscopic analysis control device 100.

(25) Thereby, the spectral characteristic values, such as a light absorption quantity and a light emission amount, of the sample 1 is measured by the spectroscopic analysis control device 100. Further, based on a plurality of types of parameters including a spectral characteristic value of a measured unknown sample, the concentration of the unknown sample is quantified by the spectroscopic analysis control device 100. Here, a plurality of types (5 types in this example) of parameters is received in a predetermined order in each of a plurality of parameter setting screens displayed on the display unit 160.

(26) Specifically, in the first step, measurement conditions are received in the condition setting screen. In the second step, accessory device information is received in the accessory device screen. In the third step, standard sample information is received at the standard sample screen. In the fourth step, calibration curve information is received in the calibration curve screen. In the fifth step, unknown sample information is received at the unknown sample screen. Hereinafter, each parameter setting screen and the type of a parameter are described below.

(2) Parameter Setting Screen

(27) (a) Condition Setting Screen

(28) FIG. 2 is a diagram showing an example of a condition setting screen. As shown in FIG. 2, a rectangular setting screen display area A is provided at the center of the display unit 160. After the start of the spectroscopic analysis control processing, a condition setting screen A1 is displayed in the setting screen display area A as a first parameter setting screen in the first step. In the case of FIG. 2, measurement conditions showing “unit”, “wavelength”, and “number of measurement” are received as parameters by the condition setting screen A1.

(29) The “Unit” indicates whether the spectral characteristic value is a light absorption quantity or a light emission amount. The “unit” is received by checking any one of a plurality of check boxes CB1 displayed on the condition setting screen A1 so as to correspond to the type of the “unit”. The “Wavelength” indicates the wavelength of light emitted from the light emitting unit 210 of FIG. 1. The “wavelength” is received by inputting a numerical value in the numeric input field NE1 displayed on the condition setting screen A1 so as to correspond to the type of the “wavelength”. The “number of measurement” denotes the number of executing the spectrophotometry by the spectrophotometer 200. The “number of measurement” is received by checking any one of a plurality of check boxes CB2 displayed on the condition setting screen A1 so as to correspond to the type of the “number of measurement”.

(30) At the upper portion of the display screen of the display unit 160, a strip-shaped step index display area B is provided so as to extend in the lateral direction. In the step index display area B, regardless of the parameter setting screen displayed on the setting screen display area A, a plurality of step indexes B1 to B5 respectively corresponding to a plurality of steps is constantly displayed.

(31) Of the plurality of step indexes B1 to B5, the step index corresponding to the parameter setting screen displayed in the setting screen display area A is displayed so as to be distinguishable from the other step indexes. In the example of FIG. 2, the step index B1 corresponding to the condition setting screen A1 which is being displayed on the setting screen display area A is displayed in a color different from the colors of the other step indexes B2 to B5.

(32) Further, the step index corresponding to the step in which parameters have been set and the step index corresponding to the step in which parameters have not been set are displayed in such a manner as to be further distinguishable. Specifically, the step index corresponding to the step in which parameters have been set and the step index corresponding to the step in which no parameters have been set are displayed in a different shape. In the example of FIG. 2, no parameters are set in any step. Therefore, all of the step indexes B1 to B5 are displayed in a same shape (e.g., a ribbon-like shape, such as, e.g., a pentagonal shape and a hexagonal shape).

(33) A setting button C is displayed at the lower portion of the display unit 160. When the setting button C is operated in a state in which measurement conditions are received in the condition setting screen A1, the received measurement conditions are set in an unchangeable manner. In place of the condition setting screen A1, an accessory device screen is displayed on the setting screen display area A as a second parameter setting screen. Further, the display mode of the plurality of step indexes B1 to B5 changes. Based on the set measurement conditions, the operation of the spectrophotometer 200 of FIG. 1 is controlled.

(34) (b) Accessory Device Screen

(35) FIG. 3 is a diagram showing an example of an accessory device screen. At this time, parameters in the first step have been set, and parameters in the second to fifth steps have not been set. Therefore, as shown in FIG. 3, the step index B1 corresponding to the first step is displayed in a rectangular shape, and the step indexes B2 to B5 corresponding to the second to fifth steps are each displayed in a ribbon-like shape. The step index B2 corresponding to the accessory device screen A2 displayed on the setting screen display area A is displayed in a color different from the colors of the other step indexes B1, B3 to B5.

(36) In the accessory device screen A2, the information (accessory device information) about the accessory device provided to the spectroscopic analysis device 300 of FIG. 1 is received as parameters. The accessory device is, for example, a sample cell 310 of FIG. 1. The accessory device information includes, for example, the shape and the dimensions of the accessory device. The accessory device information includes not using the accessory device. Note that since the accessory device information can be specified by the model number of the accessory device, in the example of FIG. 3, the “Model Number V” to “Model Number Z” of the accessory device are displayed as the accessory device information in the accessory device screen A2. The accessory device information is received by checking any one of the plurality of checkboxes CB3 displayed in the accessory device screen A2 so as to correspond to the type of the accessory device information.

(37) When the setting button C is operated in a state in which the accessory device information is received in the accessory device screen A2, the received accessory device information is set in an unchangeable manner. In place of the accessory device screen A2, a standard sample screen is displayed on the setting screen display area A as a third parameter setting screen, and the display mode of the plurality of step indexes B1 to B5 changes.

(38) (c) Standard Sample Screen

(39) FIG. 4 is a diagram showing an example of a standard sample screen. At this time, parameters in the first and second steps have been set, and parameters in the third to fifth steps have not been set. Therefore, as shown in FIG. 4, the step indexes B1 and B2 respectively corresponding to the first and second steps are each displayed in a rectangular shape, and the step indexes B3 to B5 respectively corresponding to the third to fifth steps are each displayed in a ribbon-like shape. The step index B3 corresponding to the standard sample screen A3 which is being displayed on the setting screen display area A is displayed in a color different from the colors of the other step indexes B1, B2, B4, and B5.

(40) In the standard sample screen A3, standard sample information on each of a plurality of standard samples is received as parameters. The standard sample information includes a set of the concentration and the spectral characteristic value. In the example of FIG. 4, the “standard sample 1” to the “standard sample 5” are displayed on the standard sample screen A3 as a plurality of standard samples. Each standard sample information is received by inputting a concentration and a spectral characteristic value in each of the numeric input fields NE2 and NE3 displayed on the standard sample screen A3 so as to correspond to the standard sample information.

(41) Here, the spectral characteristic value of a standard sample measured by the spectrophotometer 200 of FIG. 1 based on the measurement condition and the accessory device information respectively set in the first and second steps will be input into the numeric input field NE3. In the example of FIG. 4, the spectral characteristic value is the “light absorption quantity”. For the “standard sample 1” to the “standard sample 3”, the “concentration” and the “light absorption quantity” have been input to the numeric input fields NE2 and NE3, respectively.

(42) When the setting button C is operated in a state in which the standard sample information is received in the standard sample screen A3, the received standard sample information is set in an unchangeable manner. In place of the standard sample screen A3, the calibration curve screen is displayed on the setting screen display area A as a fourth parameter setting screen, and the display mode of the plurality of step indexes B1 to B5 changes.

(43) (d) Calibration Curve Screen

(44) FIG. 5 is a diagram showing an example of a calibration curve screen. At this time, parameters in the first through third steps have been set, and parameters in the fourth and fifth steps have not been set. Therefore, as shown in FIG. 5, the step indexes B1 to B3 respectively corresponding to the first to third steps are each displayed in a rectangular shape, and the step indexes B4 and B5 respectively corresponding to the fourth and fifth steps are each displayed in a ribbon-like shape. The step index B4 corresponding to the calibration curve screen A4 displayed in the setting screen display area A is displayed in a color different from the colors of the other step indexes B1 to B3 and B5.

(45) In the calibration curve screen A4, the calibration curve information indicating the order of the calibration curve is received as a parameter. In the case of FIG. 5, the “linear expression” and the “quadratic expression” are displayed as the order of the calibration curve on the calibration curve screen A4. The calibration curve information is received by checking the check box CB4 displayed on the calibration curve screen A4 so as to correspond to the type of the calibration curve information.

(46) In the calibration curve screen A4, graphs GR each indicating the relationship between the spectral characteristic value and the concentration of the plurality of standard samples set in standard sample screen A3 may be displayed. In this case, the user can easily specify the appropriate type of calibration curve information by visually recognizing the graph GR.

(47) When the setting button C is operated in a state in which the calibration curve information is received on the calibration curve screen A4, the received calibration curve information is set in an unchangeable manner. Further, a calibration curve is generated based on the set calibration curve information and the standard sample information set in the third step. Further, in place of the calibration curve screen A4, an unknown sample screen is displayed on the setting screen display area A as the fifth parameter setting screen, and the display mode of the plurality of step indexes B1 to B5 changes.

(48) (e) Unknown Sample Screen

(49) FIG. 6 is a diagram showing an example of an unknown sample screen. At this time, parameters in the first to fourth steps have been set, and parameters in the fifth step has not been set. Therefore, as shown in FIG. 6, the step indexes B1 to B4 respectively corresponding to the first to fourth steps are each displayed in a rectangular shape, and the step index B5 corresponding to the fifth step is displayed in a ribbon shape. The step index B5 corresponding to the unknown sample screen A5 displayed in the setting screen display area A is displayed in a color different from the colors of the other step indexes B1 to B4.

(50) In the unknown sample screen A5, unknown sample information indicating the spectral characteristic value of an unknown sample is received as parameters. In FIG. 6, the spectral characteristic values of a plurality of unknown samples can be received, and the “unknown sample 1” to the “unknown sample 5” are displayed as a plurality of unknown samples on the unknown sample screen A5. The respective unknown sample information is received by inputting the spectral characteristic value to the numeric input field NE4 displayed on the unknown sample screen A5 so as to correspond to the unknown sample information.

(51) Here, the spectral characteristic value of the unknown sample measured by the spectrophotometer 200 of FIG. 1 based on the measurement condition and the accessory device information respectively set in the first and second steps will be input to the numeric input field NE4. In the example of FIG. 6, the spectral characteristic value is the “light absorption quantity”. For the “unknown sample 1” and the “unknown sample 2”, the “light absorption quantity” is input to the numeric input fields NE4.

(52) In the fifth step, in place of the setting button C in FIG. 2 to FIG. 5, the Decision button D is displayed at the lower portion of the display unit 160. When the decision button D is operated in a state in which the unknown sample information is received on the unknown sample screen A5, the received unknown sample information is set in an unchangeable manner. Further, the concentration of the unknown sample is quantified based on the set unknown sample information and the calibration curve generated in the fourth step. FIG. 7 is a diagram showing an example of the unknown sample screen after the quantitation. As shown in FIG. 7, the concentration of the quantified unknown sample is displayed on the unknown sample screen A5.

(53) (f) Confirmation of Parameter Setting Screen

(54) In the second to fifth steps, there is a case in which the user wants to confirm the previously set parameters. Under the circumstances, in this embodiment, by operating the step index corresponding to the step prior to the current step, it is possible to execute the confirmation processing for displaying the parameter setting screen corresponding to the operated step index on the setting screen display area A.

(55) FIG. 8 is a diagram showing an example of the parameter setting screen in the confirmation processing. For example, in the third step shown in FIG. 4, in the case of confirming a previously set measurement conditions, the user operates the step index B1. As a result, as shown in FIG. 8, the display of the setting screen display area A is switched from the display of the standard sample screen A3 to the display of the condition setting screen A1 corresponding to the step index B1.

(56) In this state, the parameters in the first and second steps have been set, and the parameters in the third to fifth steps have not been set. Therefore, the step indexes B1 and B2 respectively corresponding to the first and second steps are each displayed in a rectangular shape, and the step indexes B3 to B5 respectively corresponding to the third to fifth steps are each displayed in a ribbon-like shape. Further, the step index B1 corresponding to the condition setting screen A1 displayed in the setting screen display area A is displayed in a color different from the colors of the other step indexes B2 to B5.

(57) The user can confirm the measurement conditions by visually recognizing the condition setting screen A1 displayed in the setting screen display area A. Note that by operating the step index B2, the user can switch the display of the setting screen display area A to the display of the accessory device screen A2. Further, the user can switch (return) the display of the setting screen display area A to the standard sample screen A3 in which the parameter setting is being performed by operating the step index B3.

(58) When the parameters set in the previous step are changed, parameters set in the later steps may become inappropriate. Therefore, in the parameter setting screen in which the confirmation processing is being performed, the change of the previously set parameters is not received. With this, it is possible to prevent the preset parameters from becoming inappropriate.

(59) On the other hand, there is a case in which it is desired to change parameters set in the previous steps. Under the circumstances, during the the confirmation processing, a resetting button E is further displayed on the parameter setting screen corresponding to the step in which parameters have already been set. When the user wants to change the parameters set in any step, the user operates the resetting button E on the parameter setting screen in which the confirmation processing is being performed corresponding to the step.

(60) In this case, the parameters corresponding to the step in which the resetting button E is operated is canceled, and the parameters corresponding to all of the steps later than the step are canceled. Further, the parameter setting screen corresponding to the step in which the resetting button E is operated is displayed in the setting screen display area A. As a result, the user can reset parameters to be changed. Further, since the parameters corresponding to the subsequent steps are also reset, it is possible to prevent the previously set parameter from becoming inappropriate.

Note that when the unknown sample information is not held in Step S54, the determination is not instructed in Step S57.

(140) Steps S53 to S57 are repeated until resetting is instructed in the confirmation processing of Step S56 or until the determination is instructed in Step S57.

(5) Effects

(142) According to the spectroscopic analysis control device 100 of this embodiment, inputting of parameters in each step is received from the parameter setting screen corresponding to the step displayed on the display unit 160. When the previously set parameters are changed, there is a case in which parameters corresponding to the subsequent step become inappropriate due to the change of parameters. Under the circumstances, every time the acceptance of inputting of parameters corresponding to one step is completed, the received parameters are set in an unchangeable manner, and the parameter setting screen corresponding to the subsequent step is displayed on the display unit 160. This can prevent parameters corresponding to the subsequent step from becoming inappropriate due to the change of parameters corresponding to the previous step. Further, the user can easily input predetermined parameters in a predetermined order without mistaking the order of inputting of the parameters.

(143) Further, the step index corresponding to the current step is displayed in the display unit 160 in such a manner so as to be distinguishable from the other step indexes. Therefore, the user can easily confirm that the currently inputting parameters are parameters corresponding to which step in all steps. Therefore, the user is not required to switch the parameter setting screen displays to confirm the current step. As a result, the operability of the spectroscopic analysis control device 100 can be improved.
