DESCRIPTION
Use Thermo Scientific™ Dionex™ IonPac™ CP Cation Polisher Columns (CP1 Na+, CP2 H+) when analyzing anions in matrices that contain high levels of multivalent cations to reduce deposition of contaminants. Metals and other cations can precipitate on guard and analytical columns or suppressors, which can lead to performance issues such as poor peak shapes or poor recoveries for some anions. Well suited for phosphate analysis with metallic contaminants, these columns extend column and suppressor lifetimes.
