Dionex 060142 Carbopac PA20 Ion Chromatography IC Column Cartridge

The Dionex 060142 Carbopac PA20 Ion Chromatography IC Column Cartridge is a specialized polymer-based analytical component designed for high-capacity anion exchange separations within Thermo Scientific Dionex Integrated Ion Chromatography Systems. Supplied with the matching Dionex 060144 guard cartridge to protect the internal bed media, this unit optimizes column longevity while facilitating precise analysis of neutral carbohydrates, glycans, and polymeric organic acids using conductivity detection with anion-exchange suppression chemistry. As a strong base anion exchange medium, the PA20 composition features a quaternary ammonium functionalized surface that captures anionic species efficiently, offering superior durability for alkaline conditions and stable retention with sodium hydroxide elution gradients. Integrating these twin components ensures consistent baseline stability and high peak resolution for complex mixture analysis required in routine pharmaceutical quality control, biotech research, and food safety testing protocols where precise quantification of charged molecules is essential.
