Dionex ICS-1100 Ion Chromatography System
2 Doc. 065289-03 10/12
A typical IC analysis consists of six stages (see Figure 1-1).
1. Eluent Delivery
• Eluent, a liquid that helps to separate the sample ions, carries the
sample through the ion chromatography system. The Dionex ICS-
1100 is an isocratic delivery system. This means that the eluent
composition and concentration remain constant throughout the run.
2. Sample Injection
• The liquid sample is loaded into a sample loop either manually or
automatically (if an automated sampler is installed). When triggered,
the Dionex ICS-1100 injects the sample into the eluent stream.
• The pump pushes the eluent and sample through the guard and
separator columns (chemically-inert tubes packed with a polymeric
resin). The guard column removes contaminants that might poison the
separator column.
