CDS Empore 2252 and 2352 Environmental Anion Disks are polymer-based strong anion exchange solid phase extraction (SPE) disks with a 12 μm particle size for extracting negatively charged ions from aqueous samples. These SPE disks are ideal for removing humic and fulvic acid interferences and are compatible with EPA Methods 548.1, 552.1, and others. With a wide pH range of 1–14, they offer strong ion-exchange performance for environmental water analysis and related applications.
