Project Description

Cation exchange chromatography

SPE-SCX and SPE-WCX sorbents are polymer microspheres with functional sulfate or carboxyl groups based on a mixed mode of cation ion exchange and hydrophobicity interaction, they are used to separate and analyze alkaline compounds such as amphetamines, melamine, chloropheniramine, phencyclidine, etc.

Due to high surface area of the microspheres and ion exchange capacity of sulfate groups, SPE-SCX and SPE-WCX can effectively and steadily adsorb basic compounds, and retain them well in comparison with known products from the current leading companies.

SPE-SCX and SPE-WCX sorbents hold the stability of the bonded phase across the entire pH range of 1 to 14 and greatly widen the conditions for separation exploration. Furthermore, SPE-SCX and SPE-WCX columns have the unique monodisperse sorbents which enhance flow rate stability and improve recovery thus providing good product reproducibility on large scale manufacturing.
