The present disclosure relates to a computer-implemented method for analyzing a product stream of a chemical reaction. The method includes withdrawing a portion of the product stream of the chemical reaction from a reactor, the portion of the product stream having a volume of less than about 200 μL. The method further includes mixing the portion of the product stream with a diluent to produce a sample and then transferring the sample to a liquid chromatography device. A measured chemical profile is then developed, via the liquid chromatography device, which can be used for process monitoring or real time decision making. In some embodiments, the method can include adjusting a reaction condition in the reactor based on differences between the measured chemical profile and a desired chemical profile.

Device information representing a configuration of each analysis device is acquired by a device information acquirer. Schedule information representing a use schedule of each analysis device is acquired by a schedule information acquirer. A sample analysis method is acquired by an analysis method acquirer. An analysis device that is fitted to the analysis method acquired by the analysis method acquirer and is usable is selected by a device selector from among a plurality of analysis devices based on the device information acquired by the device information acquirer and the schedule information acquired by the schedule information acquirer. Identification information for identifying the analysis device selected by the device selector is presented by a presenter.

To suppress generation of dew condensation in temperature control space when heating temperature control is performed. In an apparatus, an air temperature control part for cooling or heating air in temperature control space has a first temperature control element for performing at least cooling of air, and a second temperature control element for performing at least heating of air downstream of the first temperature control element. In this manner, when heating temperature control is performed, cooling and dehumidification of air taken in from an air intake portion can be performed by the first temperature control element, and then heating of the dehumidified air can be performed by the second temperature control element.

Exemplary embodiments provide methods, mediums, and systems for building and executing a chromatography workflow. According to the techniques described herein, the steps of the workflow may be arranged into an order and separated by gates and/or transitions. The transitions may represent locations in the workflow where responsibility or stewardship of the data in the workflow passes from one user to a different user. The steps may be represented as pages, with at least some of the steps represented by multiple different pages representing different customization options for visualizations, a configuration of the step, etc. By selecting pages for the various steps and connecting at least some of the steps with transitions, a user can build a workflow very quickly and efficiently. The resulting workflow supports improved auditing, enforces access rights, and improves workflow visualization, among other advantages.

The state between a liquid sending pump and an analysis flow path is switched between a connection state and a disconnection state. In the connection state, a sample is injected into the analysis flow path, and a scheduled analysis is executed. When a variation range of a liquid sending pressure applied by the liquid sending pump exceeds a threshold value, a liquid sending failure is detected. In a case where a liquid sending failure is detected, the sample analysis in execution is interrupted, and the state between the liquid sending pump and the analysis flow path is put in the disconnection state. Further, a purge operation is executed. After the purge operation ends, a confirming operation of confirming whether a liquid sending failure is detected is executed. When a liquid sending failure is not detected, a non-injection analysis in which a mobile phase is sent into the analysis flow path by the liquid sending pump under a condition that enables removal of a sample in the analysis flow path is executed. A sample analysis is restarted after the non-execution analysis.

An analysis system includes a setting device, an execution device, a determination device, and a notification device, and analyzes a sample by combining functions of a plurality of units. The setting device sets an analysis condition for each of the plurality of units. The execution device can execute the function of each of the plurality of units prior to the analysis of the sample. The determination device determines whether preparation for starting the analysis is completed for each of the plurality of units based on a comparison between a state of the unit and the analysis condition corresponding to the unit. The notification device notifies an analyst of a determination result by the determination device.

Described are techniques for performing automated maintenance evaluations on a gas chromatograph (GC) or a gas chromatograph-mass spectrometer (GC-MS). Systems and methods are described for directing an injector of a GC or GC-MS instrument system to autonomously inject a diagnostic material sample into a material analysis chamber and initiate a scientific analysis to formulate a set of results. The systems and methods further include the instrument system analyzing the set of results generating one or more output reports.

A main controller 201 of a main substrate 20 performs serial communications with a sub controller 214 of each flowrate control substrate 21. The flowrate of the carrier gas is controlled with the flowrate control circuit 213 under the control performed by each sub controller 214. Thus, the main controller 201 only needs to execute the processing of performing the serial communications with each sub controller 214. As a result, the processing executed by the main controller 201 can be reduced, and the processing executed by the main controller 201 is less likely to overwhelm its processing capability even when the number of flowrate control substrates 21 is increased. In addition, a signal line 40 between the main controller 201 and each sub controller 214 can be made long. Thus, the distance between the main substrate 20 and each of the flowrate control substrates 21 can be made long.
