The S 151-AG Ion Chromatography System is a quaternary gradient ion chromatography system based on the S 150 ion chromatography module consisting of an integrated column oven and a conductivity detector configured for cation analysis. The system is completed by the Sykam S 1130 IC quaternary gradient pump and the S 5300 IC autosampler. With the added feature of gradient elution for complex separation challenges but also for automatic column regeneration procedures after sample matrix induced deterioration of column performance, the S 151-AG Ion Chromatograph is built for analyzing complex samples on a routine basis. With the Clarity chromatography data handling software, the S 151-A ion chromatograph is the optimal solution for daily routine analysis of anions. A range of Sykam anion separation columns completes the S 151-A Ion Chromatograph into a “fit for the application” easy to operate ready to use system.
