Abstract

The invention relates to a fully automatic array solid-phase extraction device. The device is composed of a three-way solenoid valve, a six-way valve, a clamping device, a sample injection pressure head assembly, an elution pressure head assembly, an array disc, and a solid phase extraction column. The device is a new type of automatic array solid phase extraction device, which can automatically concentrate, enrich and purify multiple liquid samples for subsequent separation and analysis by high performance liquid chromatography. The device is suitable for automatic solid phase extraction pretreatment of a large number of liquid samples.

Description

technical field [0001] The invention belongs to the field of analytical instruments, in particular to a fully automatic device for sample pretreatment. The device is a new type of automatic array solid phase extraction device. Using program control, the quantitative absorption, sample loading, cleaning and elution of samples are completed. The device is suitable for automatic solid phase extraction pretreatment of a large number of liquid samples. Background technique [0002] Solid Phase Extraction (SPE for short) is a sample pretreatment technology developed since the mid-1980s. Developed from the combination of liquid-solid extraction and liquid chromatography. It is mainly used for the separation, purification and enrichment of samples. The main purpose is to reduce sample matrix interference and improve detection sensitivity. [0003] SPE technology is based on the theory of liquid-solid phase chromatography. It uses selective adsorption and selective elution to en...
