Product Description
PSA (Ethylenediamine - N - propyl) selectivity is similar to NH2, at the same time can be used as a positive phase or reverse phase cartridge, the polarity stronger than C18 more and weaker than silica gel, and a wider range of medium polarity or many kinds of compounds in different system has good selectivity. PSA has two NH2, pKa values are 10.1 and 10.9 respectively. PSA have stronger ion exchange capability than NH2 cartridge.
Features
1. Higher capability than NH2 sorbent
2. Effectively removing interferences in food samples
Extracting non-polar compounds
NY/T 468-2006 Determination of residual clenbuterol in animal tissues gas chromatography/mass spectrometry
APPLICATION
PSA cartridges can be produced with metal ions , used for extraction of metal ions. PSA can effectively remove the influence the detection of pesticide residues in food of fatty acids (oleic acid, palmitic acid, linoleic acid, etc.), organic acids, some polar pigments, metal ions and sugar and other distractions.
