title: Determination of urinary oxalate by ion chromatography: preliminary observation.
abstract: The technique of ion chromatography was applied to determine oxalate concentrations in unprocessed urine. The minimal detectable limits of oxalate was 1 microgram./ml. (11 mumole/liter), the within-run imprecision (Sw) was 2.3 per cent and the total imprecision (St) was 4.9 per cent. Ion chromatography can be used for the simple, accurate and direct measurement of urinary oxalate.
