In order to enable concentrations of components to be measured to be accurately calculated even when higher boiling compounds are contained in a test gas, a gas analysis device that analyzes components to be measured that are contained in a test gas using a light spectrum obtained by irradiating light onto the test gas is provided with a calibration curve data storage section in which is stored first calibration curve data in which effects on concentrations of the components to be measured from higher boiling compounds whose boiling point is higher than a heating temperature of an analyzer into which the test gas has been introduced have been corrected, and with a concentration calculation section that calculates concentrations of components to be measured using the first calibration curve data.

An optical measurement instrument is an integrated instrument that includes an optical cavity with a light source, a sample cuvette, and an optical sensor. The light source and sensor are on a bench that is on a translational or rotational mechanical platform such that optical beam can be moved to multiple sample containers. Each sample containers holds a distinct microorganism-attracting substance and a portion of a fluid sample containing an unknown microorganism. Each distinct microorganism-attracting substance is configured to bind with a single type of microorganism. The unknown microorganism in the fluid sample binds with the distinct microorganism-attracting substance in a single sample container. The instrument incubates the microorganism in the single sample container and detects the presence of the microorganism in the single sample container to thereby simultaneously identify the unknown microorganism.

A measurement device includes: a container into which sample gas is to be injected; a liquefaction mechanism configured to liquefy the sample gas in the container; a near-infrared probe extending from inside to outside the container; and a near-infrared measuring instrument configured to measure an absorbance spectrum of the sample gas in a state of being liquefied by the liquefaction mechanism, via the near-infrared probe.

Methods and systems of performing an assay. A system for performing an assay includes an enclosure defining a temperature-controlled space. An imaging system, an actuator and a dispenser are disposed within the space. The actuator receives a well plate having wells. The actuator is to move the well plate relative to the imaging system to enable the imaging system to obtain image data of one of the wells. The dispenser includes a pump, an outlet and a reservoir holder to receive a reservoir containing a compound. The pump is to be fluidly coupled to the reservoir and an outlet. The pump is to pump the compound from the reservoir through the outlet into one of the wells. The system also includes a controller. The controller is to cause the dispenser to dispense the compound into the first one of the wells while the imaging system obtains the image data.

A thermostatic module of a compact gas sensing device and a compact gas sensing device are disclosed. The thermostatic module includes a housing unit, a thermal insulation unit, a heat conducting unit, a temperature sensor, a heater and a control circuitry board. The thermal insulation unit is placed inside a first accommodation space provided by the housing unit, and forms therein a second accommodation space in which the heat conducting unit is placed. The interior of the heat conducting unit forms a third accommodation space where gas sensor modules can be housed, and also a gas passage channel. The heater generates and transfers heat to the heat conducting unit, whose interior temperature is constantly probed by the temperature sensor and input to the control circuitry board which dynamically adjusts the heating power by the heater to make sure the measured temperature is always stabilized around a preset target value.

A method of analysing an at least partially transparent object, such as a gemstone, includes fixing the object in a holder; immersing the object in the holder in an immersion material; and analysing internal and/or external features of the object. Analysing comprises visualizing an internal and/or external portion of the object using light rays while the object is immersed in the immersion material, and determining characteristics of the object based on the visualized internal and/or external portion of the object. During the analysing step, the difference between the refractive index (RI) of the immersion material and the RI of at least an immersed portion of the holder, which is in contact with the object, is less than 0.3.

A lateral flow diagnostic testing apparatus including a measurement assembly in which a cartridge is loaded and which is inclined with respect to a main body housing in a lateral flow direction of the cartridge is disclosed. The main body housing and the measurement assembly is rotatably hinge-coupled to adjust an inclination angle. The inclination of the measurement assembly is adjustable by an inclination driving unit. A vibration actuator can be further included on a cartridge loading surface. In addition, a heating unit fixed to face the cartridge can be further included.
