The S 155-C Cation Chromatography System is a table-top ion chromatograph. It is the economical solution for a fully functional cation chromatography system as single integrated pre-configured unit. The S 155-C contains an isocratic ion-chromatography pump, a manual injector, a column-oven, and a conductivity detector. For low sample throughput and educational purposes, the S 155-C ion-chromatograph is the entry level system, without compromising analytical performance. The consideration that the user could make for any options for the S 155-C ion chromatograph is to choose an additional eluent selection valve and/or inert gas supply connection for the eluent bottle(s).
