Objective: Five methods for oxalate analysis in urine are compared with respect to reliability, accuracy, and practicability. Results: Suppressed and unsuppressed ionchromatography, as well as the enzymatic Sigma-Kit, achieve low coefficients of variation for the within-batch imprecision (1.1-8.0%)
A new method for the determination of oxalic acid in urine, which does not require isolation of oxalic acid, was developed by derivatizing oxalic acid and separating and quantitating the product by automated liquid chromatography.
