AB  - A novel suppressor unit for capillary ion chromatography was designed to reduce 
      the background conductivity and at the same time to increase the analyte signal. 
      Regeneration of the suppressor was carried out on-line by passing an appropriate 
      acidic solution through the column to displace the accumulated eluent cations. By 
      using two 6-port microswitching valves and two packed capillary column 
      suppressors, the background conductivity of sodium carbonate-bicarbonate mobile 
      phase was maintained at low conductivity for continuous chromatographic runs, and 
      the detection limits at low ppb levels were achieved. The relative standard 
      deviations (RSDs) for the retention time, peak area and peak height of six common 
      inorganic anions (0.05 mM each of F(-), Cl(-), NO(2)(-), Br(-), NO(3)(-) and 
      SO(4)(2-)) were between 0.5-0.9, 1.1-4.6 and 0.7-4.9%, respectively. The present 
      system was successfully applied to the determination of inorganic anions in river 
      water and tap water samples.
