摘要： A high-performance liquid chromatograph apparatus of the present invention can obtain a similar separation effect as that obtained in a constant velocity gradient elution method and shorten a measuring time. When a data processor (13) generates a converted constant pressure gradient program based on a trace of past pressure values, a pressure value trace file stored in a pressure value trace storage unit (13a) is selected and displayed on a display and a pressure value is set. A constant pressure gradient program converting unit (13b) converts a constant velocity gradient program stored in a constant velocity gradient program storage unit (13c) to the constant pressure gradient program and numerals according to the converted constant pressure gradient program are displayed. A liquid feed part (5, 6) of a liquid feed pump (4) is controlled via a flow velocity setting unit (13d) and a mixing ratio setting unit (13e) according to the constant pressure gradient program displayed on the display.

摘要： Provided is a liquid chromatograph system and method configured to accurately obtain measurements by minimizing deviations in measurements due to a transfer from one measurement method to another measurement method. An aspect of the system and method includes minimizing deviations in measurements when a measurement method from a measurement system of a liquid chromatograph is transferred to measurement system under high pressure and high velocity. Such a transfer includes deviations due to differences in analysis conditions. The present subject matter uses a dwell volume value so as to minimize a deviation of measurement result due to methods before and after transfer.

摘要： This liquid feeding system has the first and second pumps each of which is provided with a plunger. Liquid sucked through each of the pump suction ports is discharged out of the discharging port through the first pump and/or second pump. Under the starting operation mode, the second pump is stopped and only the first pump is operated. When the discharging pressure at the discharging port reaches up to a predetermined value, the starting operation mode is changed over to the normal operation mode. Under the normal operation mode, the first pump is stopped and only the second pump is operated.

摘要： A chromatographic analyzer is provided for facilitating curve fitting by means of the linear least-square method for a chromatogram that contains a plurality of overlapping peaks. The present invention is characterized by a chromatographic data processor for executing data processing of a chromatogram obtained by separating a sample to be measured using a column and detecting the separated sample, wherein fitting processing is executed to each peak in an arbitrary time region having the plurality of peaks of the chromatogram starting from the front side of the time region or from the back side of the time region, and the processed peaks are subtracted from the chromatogram in the time region so that the plurality of peaks in the chromatogram can be separated from one another. Thus, the plurality of overlapping peaks, particularly three or more overlapping peaks in the chromatogram can be easily separated from one another only by defining some setting conditions.
