Bond Elut PSA Plates

Bond Elut PSA is an alkylated amine with two different amino functionalities and slightly higher pKa and ionic capacity than Bond Elut NH₂ for polar compounds.

Alternative choice to Bond Elut NH₂ for polar compounds
Higher ionic capacity than NH₂

It 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. 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.
