CDS Empore 2271 Environmental Chelating Disks utilize a PSDB-iminodiacetic acid chelating resin with a 12 μm particle size, designed for the extraction of divalent metals and other divalent cations from aqueous samples. These solid phase extraction (SPE) disks offer high capacity depending on pH and ion conditions. Typical relative selectivity is: Pb > Cu > Cd > Co > Fe > Ca > Sr. Suitable for environmental monitoring and trace metal analysis.
