Summary:In order to, in a chromatograph sampler, regulate the pressure of a sample fluid filled in a constant volume tube to be as constant as possible and ensure the reproducibility of measurement, the chromatograph sampler is configured to provide a bypass line between a sample introduction line and a sample discharge line in parallel with the constant volume tube, and when filling the sample fluid in the constant volume tube, flow the sample fluid also through the bypass line in parallel.
