Abstract
A two-dimensional liquid chromatograph system includes a first dimension analysis part, a second dimension analysis part, a second dimension feeding device, a fraction introduction part, a shift gradient program creation part, a liquid feeding control part, and a shift timing adjustment part. The shift gradient program creation part is configured to create a shift gradient program for causing the second dimension feeding device to execute shift gradient liquid feeding. The shift timing adjustment part is configured to adjust a shift timing to each stage in the shift gradient program created by the shift gradient program creation part based on a preliminary chromatogram acquired by the first dimension detector before the series of analysis operations for the sample to be analyzed.
