History of Chemical Suppression Leading the Way in Chemical Suppression Packed-Bed Chemical Suppressors Hollow Fiber Suppressors In this brochure, Dionex invites you to learn more about suppression technology and advances in ion analysis. Dionex introduced packed-bed chemical suppression in 1975, and modern ion chromatography was born. Chemical suppression was revolutionary because it reduced background conductivity, enhancing ion detection. With packed-bed chemical suppression, chemists achieved sensitivity and selectivity from low parts-per-billion (µg/L) to parts-per-million (mg/L) levels....

Technology MicroMembrane Suppressor A MMS uses a pair of membranes separating a central eluent chamber from regenerant chambers on either side. The chambers are filled with functionalized ionically charged screens. In an anion MMS the membrane itself as well as screens are cation exchangers in the acid form. In a cation MMS the charge is reversed. The Dionex MMS had substantially increased capacity compared to the hollow fiber suppressor, allowing continuous operation with moderate to strong eluents. The MMS was also more robust. AutoRegen® for MMS Introduced in 1987, the AutoRegen module allows...

Packed-Bed Chemical Suppressors (SC-1 and SC-2) In 1975 Dionex changed the face of Ion Analysis forever – packed bed chemical suppression was introduced to chemists worldwide. Chemical suppression was revolutionary because it reduced background conductivity and simultaneously enhanced the detection of ions; however, the suppressor needed to be periodically taken off-line to be regenerated. Hollow Fiber Suppressor (FS1 and FS2) Improving on the limited capacity of the packed-bed chemical suppressors, Dionex introduced hollow fiber suppressors in 1981 which allowed continuous regeneration, eliminating...

Atlas Suppressor Suppressor Availability An Atlas suppressor uses a small column body packed with a series of monolithic ion exchange disks through which the eluent is passed. The ends of the column body are separated from regenerant chambers by ion exchange membranes. The regenerant chambers contain electrodes that are used to generate the regenerant ions from water. When current is applied to the electrodes, an electric field pushes the regenerant ions lengthwise through the column body counter-current to the eluent flow. As Dionex advances IC technology over the years, some suppressors are...
