Copure® PSA Primary-Secondary Amine

Similar to NH2, PSA (Primary-Secondary Amine) has weak anion exchange and normal phase retention capabilities. PSA's two amine groups (pKa 10.1 and 10.9) provide a greater ion exchange capacity and can extract polar compounds through amine bonds. Additionally, PSA forms complexes with metal ions, allowing for the retention of certain metal cations.
