Summary:The instrumentation and method of analysis of 30 natural water samples by ion chromatography is described and compared to analyses for F, Cl, NO3 and SO4 by presently used techniques. Reported detection limits for the ion chromatographic technique are one to two orders of magnitude below routine methods, e.g. F 3 p.p.b., Cl 0.01 p.p.m., NO3 0.05 p.p.m. and SO4 0.05 p.p.m. Precision estimates obtained from 11 replicate analyses of synthetic solutions with widely different concentrations yielded <3% relative standard deviation for F, NO3, and SO4, and <6% for Cl. An inter-anion interference test indicated that, at pH = 6, analysis of low concentrations of any one of the four anions was not affected by large concentrations of the other three. [R.J.L.C.]
