    摘要: A controller for controlling the operations of an autosampler, a sample push unit, and a make-up unit includes a pump stop timing setting unit for setting a first timing T1 of completion of dilution of a sample, and a subsequent second timing T2 of completion of trapping of a sample in the trap column, a dilution control unit for causing a solvent delivery pump for make-up of the make-up unit to operate, and for stopping operation of the solvent delivery pump for make-up at the first timing T1 set by the pump stop timing setting unit, and a sample push control unit for causing a solvent delivery pump for sample push of the sample push unit to operate, and for stopping operation of the solvent delivery pump for sample push at the second timing T2 set by the pump stop timing setting unit.

    摘要: Before start of analysis, a user inputs pipe capacity difference relative to reference pipe capacity and separation conditions, such as a mobile phase flow rate. A control unit calculates retention time shift from the pipe capacity difference and the flow rate. The control unit controls sample injection and data processing units so as to start collection of chromatogram data when a correction time has passed from the time point of sample injection in the case in which the value of the retention time shift is a positive value, and to perform sample injection when a correction time has passed from the time point at which the collection of chromatogram data is started in the case in which the value of the retention time shift is a negative value. Retention time shift caused by difference in the pipe capacity is corrected even when the mobile phase flow rate is different.
