HA-01 Automatic Solid Phase Extraction (SPE)

Introduction

Preval SPE automatic solid-phase extraction system is a large capacity closed three-dimensional vertical solid-phase extraction system, without manual intervention can complete all the steps of solid phase extraction, solid phase extraction column, the activation, sample addition, leaching and elution experiment steps. With the method of positive hydraulic injection control liquid velocity and precision, to ensure that the liquid transmission accuracy and reproducibility.

Feature

Solid phase extraction technology based on the theory of liquid - solid chromatography, adopt the way of selective adsorption, selective elution so that it is separated from the sample matrix and interfering compounds. The basic principle of SPE and HPLC of the same but different, SPE is mainly used in the sample separation, purification and concentration, thereby reducing the sample matrix interference, improve the detection sensitivity.
