Thermo Fisher, 303349, Dionex™ IonPac™ CS21-Fast-4μm Analytical and Guard Columns

Guard Column, Dionex IonPac CS21-Fast-4µm Microbore Analytical Column, 22 µeq, 30 mm Resolve quaternary amine cationic polar pesticides including chlormequat, mepiquat, paraquat, and diquat with the Thermo Scientific™ Dionex™ IonPac™ CS21-Fast-4μm column. The unique selectivity of the Dionex IonPac CS21-Fast-4μm column allows it to resolve trace amounts of cationic polar pesticides in high ionic strength matrices within approximately fifteen minutes using an electrolytically generated MSA gradient. Quaternary amines are eluted away from matrix cations, making the Dionex IonPac CS21-Fast-4μm column ideal for IC-MS/MS applications where matrix ions are diverted to waste. Column Construction: PEEK
