title: Recent advances in ion chromatography suppressor improve anion separation and detection.
abstract: The Alltech DS-Plus suppressor improves and simplifies anion analysis by suppressor-based ion chromatography (IC). In addition to suppressing the mobile phase and enhancing the analyte signal, the DS-Plus suppressor removes carbonic acid from the suppressor effluent when carbonate-hydrogencarbonate mobile phases are used, reducing the water dip that interferes with early eluting peaks, increasing detection sensitivity, and enabling carbonate-hydrogencarbonate gradients. The ability to operate with carbonate-hydrogencarbonate gradients places exceptional separating power in the mobile phase, forgoing the need for expensive columns with special selectivity. Continuous operation and solid-phase chemistry eliminates the need for external regenerants, switching valves, and multiple operating modes.
