Determination of Urinary Oxalate by Ion Chromatography: Preliminary Observation

Abstract
The technique of ion chromatography was applied to determine oxalate concentrations in unprocessed [human] urine. The minimal detectable limits of oxalate was 1 .mu.g./ml. (11 .mu.mole/l), the within-run imprecision (Sw) was 2.3% and the total imprecision (St) was 4.9%. Ion chromatography can be used for the simple, accurate and direct measurement of urinary oxalate.
