DESCRIPTION
Used on the Thermo Scientific™ Dionex™ OnGuard™ Workstation, Dionex OnGuard 18 Gauge Needles connect to the Leur-lock fitting that attaches to the Dionex OnGuard II Cartridges and direct the flow of liquid into collection vials. Dionex OnGuard II Cartridges remove sample matrix interferences encountered in many ion chromatography (IC) applications. Up to 12 cartridges can be placed on the vacuum-driven Dionex OnGuard™ Workstation for sample pretreatment in parallel.
