Dionex ICS-2100 Ion Chromatography System

Description

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.

The Dionex ICS-2100 is an integrated ion chromatography system containing an eluent generator, pump, injection valve, column heater, and conductivity detector. Other system components, including a guard column, separator column, and suppressor vary, depending on the analyses to be performed. The Dionex ICS-2100 can be configured with a vacuum degas assembly for online eluent degassing. If desired, the second eluent generator power supply can be configured to power an auxiliary electrolytic device, such as a water purifier. An optional second high-pressure valve (6-port or 10-port) can be installed for sample preparation applications. Dionex ICS-2100 operation can be controlled in one of two ways:

• Remotely, with a personal computer running Microsoft® Windows® Vista or Windows XP and Chromeleon software (version 6.80 SR6a or later). Chromeleon also provides data acquisition and data processing functions.

• Locally, with the front panel LCD touch screen. The touch screen is used for instrument control only. It does not provide data acquisition or data processing functions. An analog output on the rear panel can be connected to a separate data acquisition device.
