Brief Intro Of Solid Phase Extraction

As a fast and efficient sample preparation technique for cleanup and concentration for analysis of HPLC, GC, TLC, UV, IR, Solid Phase Extraction, as we called “SPE”, is also an excellent tool used by most chromatography in the lab nowadays.

SPE is well designed to extract, partition, and adsorb one or more components from a liquid phase onto a stationary phase. The principle can be described like that: by an increase of elution strength of the eluent, an adsorbed substance can be removed from the simple adsorbent perfectly.

Compared to classical liquid-liquid extraction, SPE has lots of Advantages: lower consumption of solvents and the sample costs, high consistency of sample handling, more time savings and specific selectivity. SPE is put into practice by more and more scientists because it can not only extend a chromatographic system’s operation life but lessen the demand on analytical instruments.

Being used in sample separation and pretreatment, Hawach SPE Cartridges are divided into silica gel, polymer, adsorption type, the special cartridge according to matrix type. The cartridge has three parts: medical PP empty tube, medical PE sieve plate, and a fixed adsorbent.
