Description

technical field

[0001] The invention relates to a liquid chromatograph, in particular to a portable liquid chromatograph. Background technique

[0002] High performance liquid chromatography (HPLC for short) is a technique widely used in separation and analysis. It has the advantages of high separation efficiency, good selectivity, high detection sensitivity, and fast analysis speed. The wide application in environmental analysis and life analysis has made high performance liquid chromatography one of the core technologies of modern analytical science. In recent years, liquid chromatography instruments have been ranking first in the demand for analytical instruments.

[0003] Existing high performance liquid chromatography generally consists of infusion system 01, sampling system 02, chromatographic column 03, detection system 04, data recording and processing system 05, and temperature control device 06. The detector, pump and chromatographic column are Three key component...
