Solid phase extraction cartridges, Bond Elut™ PSA
: VARIAN
Bond Elut™ PSA is an alkylated amine sorbent that contains two different amino functionalities, one secondary and one primary. This gives a slightly higher pKa and ionic capacity compared to Bond Elut™ NH₂. The PSA functional group is a very effective bidentate ligand and is therefore an excellent sorbent for chelation applications. PSA has a significantly higher carbon load than most amino functional sorbents and thus is a better choice for polar compounds, which retain too strongly on Bond Elut™ NH₂.
- Very effective bidentate ligand
- Alternative choice for polar compounds to Bond Elut™ NH₂
- Higher ionic capacity than NH₂
