In the solid-phase extraction process, the attraction of the solid phase to the analyte is greater than that of the sample mother liquor. When the sample passes through the SPE column, the analyte is adsorbed on the solid surface, and other components pass through the column with the sample mother liquor. Finally, they are eluted with an appropriate solvent. SPE can be divided into four types based on its principles: reverse SPE (RP-SPE), forward SPE (NP-SPE), ion exchange SPE (IE-SPE), and adsorption SPE. In most cases, solid-phase extraction is applied to process liquid samples for the extraction, concentration, and purification of volatile and semi volatile compounds in the samples; When used for solid samples, the solid sample needs to be processed into a liquid state first.

Product features:

1) Each independent valve control is durable and easy to operate.

2) Anti cross contamination, anti fogging glass vacuum chamber.

3) Can be equipped with a large capacity collector, a fast concentration and drying device, and can process samples in batches.

4) We suggest that you choose our company's AP series oil-free vacuum pump when purchasing solid-phase extraction.
