Polymer-based cationic Ion chromatography column

Polymer-based column for sugar analysis, using aqueous Size Exclusion (GFC) + Ligand exchange (LX) Chromatography

Measure trace bromate and other oxyhalides in drinking water, ground water, wastewater, and other diverse sample matrices with the Thermo Scientific™ Dionex™ IonPac™ AS23 carbonate eluent anion-exchange column.

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 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. 

Rezex™ columns achieve separations based on multiple modes of interaction including ion-exchange, ion-exclusion, size exclusion, reversed phase, and partition. From drug formulation analysis to quality control testing of finished food products, to bioethanol fermentation monitoring Rezex columns consistently provide accurate and reproducible results.Choose Rezex for excellent resolution and reproducibility of sugars, starches…
