Abstract

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. Another aspect includes calculating a correction value when there is a deviation in the measurement result, and automatically reflecting the correction value for the method transfer.

Claims (18)

1. A liquid chromatograph system comprising:

an injecting device for sucking sample solute;

a liquid delivering device for delivering the sample solute;

a column for separating the sample solute;

a detecting device for detecting the separated sample solute;

a first processing device for processing the detection result; and

a panel device for displaying a liquid chromatograph based on the processed result, comprising:

a second processing device for transferring a method, wherein the transfer is from a first method for using a first column to a second method for using a second column based on data of the first column and data of the second column, and

wherein a dwell volume value is used during the transfer.

2. A liquid chromatograph system comprising:

an injecting device for sucking sample solute;

a liquid delivering device for delivering the sample solute;

a column for separating the sample solute;

a detecting device for detecting the separated sample solute;

a first processing device for processing the detection result; and

a panel device for displaying a liquid chromatograph based on the processed result, comprising:

a second processing device for transferring a method, wherein the transfer is from a first method for using a first column to a second method for using a second column based on data of the first column and data of the second column, and

wherein the panel device includes a panel for setting dwell volumes before and after the transfer.
