Solid Phase Extraction (SPE)

Solid Phase Extraction (SPE) is simple chromatography designed to extract, partition, and adsorb one or more components from a liquid phase onto a stationary phase (sorbent). Currently, SPE has become the more powerful technique available for the rapid and selective purification or concentration of samples before analysis in gas chromatography and liquid chromatography.

ChinaPeptides & Benefit Tech. has developed the class technology in microsphere preparation and surface modification for providing a series of ly efficient SPE sorbents. The SPE sorbents have uniform particle sizes, optimized pore size and very chemical stability. Therefore, ChinaPeptides & Benefit Tech’s SPE sorbents readily satisfy the need for sensitivity in analyzing different materials including pesticide residues, veterinary drug residues and mycotoxin residues.

ly Uniform SPE Sorbents ChinaPeptides & Benefit Tech. can supply monodisperse SPE sorbents, which has already impacted the current SPE market traditionally relied on sorbents of broad size distribution or irregular shape. Under SEM microscope and particle size distribution as shown in Figure 1, the new series SPE sorbents by ChinaPeptides & Benefit Tech. is spherical and monodisperse with Coefficient of Variation (CV) less than 3%.
