There are four basic suppression modes for the Dionex DRS 600, Dionex ERS 500e, and Dionex AERS 500 suppressors:

NOTE

The Dionex DRS 600, Dionex AERS 500 Carbonate, and Dionex ERS 500e can also be used in Chemical Suppression Mode; however, the total suppression capacity is reduced compared to a chemically regenerated suppressor. Thermo Scientific recommends the use of a chemically regenerated suppressor such as the Dionex CRS 500 for chemical suppression applications.
