Bondesil PSA (Ethylenediamine-N-propyl)

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

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. PSA has a significantly higher carbon load than most amino functional sorbents, thus is a better choice for polar compounds, which retain too strongly on Bond Elut NH2.

Carbon Loading: 7.5%

Surface Area: 500m²/g
