SHIMSEN Styra PSA 500mg/6mL 30pcs
Part No.: 380-00859-01
SHIMSEN Solid-Phase Extraction
SHIMSEN Styra PSA is based on silica gel particles bonded with ethylenediamino-N-propyl which contain two different amino―the pKa of one is 10.1, and other is 10.9. It is similar to NH2 cartridge but has stronger ion exchange functionalities. At the same time, PSA can be used to extract metal ion due to the chelation with metal ion.
Retention mechanism: Weak anion exchange, polar interaction, chelation
Matrix: Particle size 50 μm, pore size 60 Å
Spherical silica particles with a specific surface area of 500 m2/g
Function groups: Ethylenediamine-N-propyl
Endcapped: No
Carbon load (C%): 7%
pKa: 10.1 and 10.9 (the pKa of its conjugated acid)
Application:
It can be used to separate structural isomers; extract compounds with polar groups from lipid samples, and remove polar compounds (such as carbohydrates, pigments), organic acids, phenols, etc. in pesticide residue analysis.
