2 mm and 4 mm formats for use with 2, 3, 4, or 5 mm Ion Chromatography columns and systems. The 2 mm Dionex ERS 500, Dionex ERS 500e and Dionex AERS 500 Carbonate are specially designed with reduced internal volume to ensure optimum performance with 2 mm columns and systems. - Page 10 346-6390. Outside the U.S., call the nearest Thermo Fisher Scientific office. The Dionex ERS 500 design comprises of three channels defined by two ion exchange membranes. The central channel is the eluent channel and the two side channels are regenerant channels.
