SHIMSEN Styra NH2 is an amino bonded silica cartridge and can act either as a weak anion exchanger (aqueous solutions) or polar phase sorbent (non-polar organic solutions). When conditioned with a non-polar solvent, e.g., hexane, it tends to form hydrogen bond with any molecule containing -OH, -NH, or -SH functional groups. In an aqueous environment with pH 7.8 or less, it can function as a weak anion exchanger.

Retention mechanism: Polar interaction and weak anion exchange

  • Matrix: Particle size 50 μm, pore size 60 Å
  • Spherical silica particles with a specific surface area of 500 m2/g
  • Function groups: Cyanopropyl
  • Endcapped: No
  • Carbon load (C%): 3.5%
  • pKa: 9.8 (the pKa of its conjugated acid)

 

Application:
It can be used to separate structural isomers; extract compounds with polar groups from lipid samples; remove polar compounds (such as carbohydrates, pigments), organic acids, and phenols, etc. in pesticide residue analysis.
