Dionex ICS

The Thermo Scientific Dionex™ ICS-2100 Ion Chromatography System (Dionex
ICS-2100) performs ion analyses using suppressed or non-suppressed
conductivity detection. An ion chromatography system typically consists of a
liquid eluent, a high-pressure pump, a sample injector, a guard and separator
column, a chemical suppressor, a conductivity cell, and a data collection system.

Before running a sample, the ion chromatography system is calibrated using a
standard solution. By comparing the data obtained from a sample to that obtained from the known standard, sample ions can be identified and quantitated. The data collection system, typically a computer running chromatography software, produces a chromatogram (a plot of the detector output vs. time). The chromatography software converts each peak in the chromatogram to a sample concentration and produces a printout of the results.
