Abstract: A correspondence relationship between an inspection item and an operator code assigned to each operator of an analysis unit is acquired by a correspondence relationship acquirer. 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 by a screen information acquirer. 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: A range of pH of a mobile phase that is usable for an analysis with use of each column is registered by a pH range registrar in association with identification information of each column. A pH of each mobile phase is registered by a pH registrar. A column to be used for an analysis is selected by a column selector. A chromatograph is controlled by an analysis controller such that a mobile phase having a registered pH that is out of a range of pH that is registered in association with a selected column is not supplied to the selected column. The chromatograph is controlled by the analysis controller such that an analysis is performed while a mobile phase having a registered pH that is in a range of pH that is registered in association with a selected column is supplied to the selected column.

Abstract: A data processor (10) that performs data processing on a plurality of the chromatograms stored in the data storage part (8) is provided. The data processor (10) is capable of executing automatic identification for automatically performing identification processing. In the identification processing, one chromatogram among the plurality of the chromatograms is set as a reference chromatogram, a plurality of component peaks on the reference chromatogram is set as reference peaks, and it is identified which component peaks among component peaks on other chromatograms than the reference chromatogram among the plurality of the chromatograms corresponds to each of the plurality of the reference peaks. In the automatic identification, the data processor (10) is configured to identify component peaks corresponding to each of the reference peaks by executing filtering using a reference parameter for peak parameters of each of component peaks on the other chromatograms.

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.
