SPE Column--PSA

Description：

About PSA solid phase extraction cartridge

PSA sorbent contains two different amino groups, one primary and one secondary. It gives comparatively higher pKa and ionic capacity relative to ProElut™ NH2. The PSA sorbent is an excellent choice for extracting polar compounds from non-polar solvents. The compounds that are retained too strongly on a NH2 sorbent can be effectively eluted on a PSA sorbent. In addition, the PSA functional group is a very effective bidentate ligand in chelation applications.
