CDS Empore 2251 Environmental Cation Disks are polymer-based strong cation exchange solid phase extraction (SPE) disks with a 12 μm particle size, designed for extracting positively charged ions from aqueous solutions. These disks offer effective extraction and recovery of primary, secondary, and some tertiary amines, as well as most metal cations. Suitable for samples with pH range 1–14. Not recommended for quaternary amines.
