Abstract: An online HPLC dissolution test system includes a dissolution tester and a liquid chromatograph. An autosampler of the liquid chromatograph includes at least one flow vial, a sampling needle and an injection port. The flow vial is connected to the dissolution tester via a pipe and is for storing a sample solution supplied from the dissolution tester therein. The sampling needle is for collecting the sample solution by sucking from the flow vial. The injection port is for injecting the sample solution from the sampling needle into the analysis channel. The controller of the liquid chromatograph includes an immediate analyzing execution part configured to cause the autosampler to execute immediate analyzing operation for sucking the sample solution in the flow vial with the sampling needle and directly injecting the sample solution into the injection port when the sample solution is supplied from the dissolution tester to the flow vial.

Abstract: An analyzer controlling apparatus enabling a user to correctly and easily select a method file in which analysis conditions for operating an analyzer are described. An analyzer controlling apparatus reads out a method file stored in a memory and sets an analysis condition for an analyzer. The analyzer controlling apparatus includes: image creating unit for creating an image according to a predetermined rule based on content of an analysis condition described in a method file and/or a file name of the method file and for storing the image into the memory in association with the method file; an image showing unit for reading an image out of the memory and showing the image onto a display screen; and an analysis condition setting unit for reading, out of the memory, a method file associated with an image selected by a user and for setting an analysis condition for the analyzer.

Abstract: An inspection item for an analysis unit is specified. A correspondence relationship between the inspection item and an operator code assigned to each operator of the analysis unit is acquired. Operation commands assigned to operators to be operated for execution of an inspection of the analysis unit are sequentially transmitted to the analysis unit based on the inspection item and the correspondence relationship. A request command requesting transmission of screen information representing a screen to be displayed in the display panel of the analysis unit is transmitted to the analysis unit. The screen information that has been transmitted by the analysis unit in response to the request command is acquired. The analysis unit behaves based on the operation command assigned to the operated operator and a screen responding to the behavior of the analysis unit is displayed in the display panel of the analysis unit.

Abstract: In a chromatograph, a mobile phase is supplied to any of a plurality of columns by a mobile phase supplier, and a sample is supplied to the column by a sample supplier. The sample that has passed through the column is detected by a detector. In a chromatographic control device, a flow rate of the mobile phase for the analysis with use of the column is registered by a flow rate registrar in association with column specifying information for specifying each column. The flow rate of the mobile phase registered in association with a selected column is acquired from registered content of the flow rate registrar. The chromatograph is controlled such that the analysis is performed by an analysis controller while the mobile phase is supplied to the selected column with use of the selected column and the flow rate of the mobile phase acquired by a flow rate acquirer.

Abstract: An analysis assistance device includes a chromatogram generator that generates a chromatogram using measurement data obtained from an analysis device, an area calculator that calculates an area percentage of each peak included in the chromatogram, a determiner that determines a separation state of each peak included in the chromatogram, and an analysis assistance information outputter that outputs analysis assistance information to a display. The analysis assistance information outputter includes a chromatogram outputter that outputs the chromatogram generated by the chromatogram generator to the display and also outputs information to display one peak in an identified manner when the one peak has an area percentage of not less than a predetermined threshold value, and the determiner determines that the one peak is an unseparated peak.

Abstract: Analysis control software is installed in an analysis control device. The analysis control software is the software for controlling an analysis device, and has a function of causing a display to display one or a plurality of operation images for receiving an operation for inspecting the analysis control software. In a validation device, operation commands for performing an operation on one or a plurality of operation images are sequentially generated by an inspection executor with the one or plurality of operation images displayed in the display, whereby an inspection is executed by the analysis control software.

Abstract: An organic solvent containing liquid that does not include a component to be detected by a detector is used as a first solvent, and an organic solvent containing liquid that includes the component to be detected and is adjusted to have a concentration of an organic solvent that prevents a separation column from actually holding the component to be detected is used a second solvent. Further, a mobile phase is sent while a setting value of a concentration of the second solvent in the mobile phase is changed over time with the separation column provided on an analysis flow path, and an actual concentration of the second solvent in the mobile phase is found based on a detection signal of the detector when the mobile phase is sent at each setting value.
