Abstract: The method of simultaneous determination of inorganic anions, inorganic cations and organic acids by single-column anion chromatography was described.An anion-exchange column was employed for separation with conductivity detection.EDTAwas used as eluent.The eluent pHshould be controlled in the range of 5.5-7.5.Linear plots of logarithm of the adjusted retention time of the ions vs.the logarithm of the concentration of the eluent were obtained.The detection limits, variation coefficient and calibration curve for those substances were obtained at eluent concentration of 0.5 mmol/Land pH=7.0.The method was applied to analyzing chloride.calcium and oxalic acid in Ringer's injection with satisfactory results.
