The Xenoic® XAMS membrane suppressor and the Xenoic® ASUREX automatic regenerator are designed to maximize sensitivity in anion chromatography by minimizing the eluent background conductivity and noise. The robust and flexible design of ASUREX and XAMS ensures stable routine operation together with many different brands of ion chromatography systems and conductivity detectors.
The purpose of ASUREX is to maintain a constant acidic environment in the XAMS suppressor, where the ion chromatography eluent background conductivity is suppressed. Protons continuously supplied from the ASUREX-AR1 cartridge to the XAMS suppressor are transported across the suppressor ion exchange membrane into the eluent. There protons replace the cationic counter ions in the eluent (often sodium or potassium), thereby neutralizing the eluent ions to their corresponding acids (often carbonic acid or water) which have very low conductivity
