TI  - Indirect UV detection-ion-exclusion/cation-exchange chromatography of common 
      inorganic ions with sulfosalicylic acid eluent.
PG  - 121-6
AB  - Herein, we describe indirect UV detection-ion-exclusion/cation-exchange 
      chromatography (IEC/CEC) on a weakly acidic cation-exchange resin in the 
      H(+)-form (TSKgel Super IC-A/C) using sulfosalicylic acid as the eluent. The goal 
      of the study was to characterize the peaks detected by UV detector. The peak 
      directions of analyte ions in UV at 315 nm were negative because the molar 
      absorbance coefficients of analyte anions and cations were lower than that of the 
      sulfosalicylic acid eluent. Good chromatographic resolution and high 
      signal-to-noise ratios of analyte ions were obtained for the separations 
      performed using 1.1 mM sulfosalicylic acid and 1.5 mM 18-crown-6 as the eluent. 
      The relative standard deviations (RSDs) of the peak areas ranged from 0.6 to 
      4.9%. Lower detection limits of the analytes were achieved using indirect UV 
      detection at 315 nm (0.23 - 0.98 muM) than those obtained with conductometric 
      detection (CD) (0.61 - 2.1 muM) under the optimized elution conditions. The 
      calibration curves were linear in the range from 0.01 to 1.0 mM except for Cl(-), 
      which was from 0.02 to 2.0 mM. The present method was successfully applied to 
      determine common inorganic ions in a pond water sample.
