Title:
METHOD FOR DETERMINING PIPELINE VOLUME, LIQUID CHROMATOGRAPHY SYSTEM, AND PIPELINE VOLUME DETERMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/248984
Kind Code:
A1
Abstract:
A method for determining the pipeline volume in a liquid chromatography system. The method comprises: inserting a detectable marker into a liquid flow of a liquid chromatograph (100); and by means of the time difference between a first moment at which a liquid chromatograph detector (130) detects the marker and a second moment at which a first sensor (220) detects the marker, and the flow rate of the liquid flow, determining the total volume of a pipeline between the liquid chromatograph detector (130) and the first sensor (220). By means of the method, a user can easily and flexibly determine the pipeline volume in a liquid chromatography system. In addition, further provided are a liquid chromatography system and a pipeline volume determination device.
