PSA Column Plates for Solid Phase Extraction

B&M® PSA is a silica gel-based ethylenediamine-N-propyl extraction column, PSA contains two amines whose pKa is 10.1 and 10.9, respectively. Its selectivity is similar to amines, and it can be used as a normal or reversed-phase column, with a stronger polarity than C18 and a weaker polarity than silica gel, and it has good selectivity for different compounds of medium polarity or a wider polarity range in different systems.

PSA can chelate with metal ions, used to extract metal ions. It is commonly used for pre-treatment of samples in the analysis of pesticide residues as well as organic acids, pigments, metal ions and phenols.    

Equivalent to Agilent Bond Elut PSA.
