Product Detail

Product Tags

B&M PSA is the ethylenediamine – N-propyl extraction column with silica gel, and the PSA has two amino groups, and pKa is 10.1 and 10.9 respectively. Its selectivity is similar to that of amino. As a positive phase or anti-phase column, the polarity is stronger than the C18 and weaker than the silica gel, and the various compounds with a wide range of medium polarity or polarity have good selectivity in different systems.

PSA can be used with metal ions to extract metal ions.It is often used in the preparation of samples of agricultural residues, includingorganic acids, pigments, metal ions and phenols.

Application
Soil;Water;Body fluids(plasma/urine etc.);Food;Oil
Typical Applications
Pretreatment of fatty acids, polar pigments and sugars
Chelate metal ions
