Thermo Fisher, 060557, Dionex™ IonPac™ CS17 IC Columns

Dionex™ IonPac™ CS17 IC Columns is designed for analytical cation-exchange ion chromatography of hydrophobic and polyvalent amines and common cations in complex sample matrices. This exact format is the 4 mm × 250 mm analytical column, not the 50 mm guard. Its carboxylate-functionalized polymer phase has 7 µm particles and a nominal exchange capacity of 1450 µeq. The packing uses an ethylvinylbenzene/divinylbenzene polymer with 55% DVB crosslinking. It supports acidic gradient elution for species including alkanolamines, methylamines, biogenic amines, alkyldiamines and polyamines. Suitable matrices include power-plant waters conditioned with ammonium or ethanolamine, industrial chemicals, plating baths, scrubber solutions and food samples. The recommended flow rate is 1.0–1.6 mL/min for this 4 mm analytical version, and maximum pressure is 4000 psi (275 bar). The phase tolerates acidic eluents and 0–100% compatible HPLC organic solvents, including alcohols, supporting analyte-solubility adjustments and column cleanup. Its 250 mm separation bed provides resolving length for more complex amine mixtures. The column is intended for compatible Dionex ion chromatography systems and can be paired with the matching CS17 guard to protect the analytical packing from sample contaminants.
