Determination of oxalate in urine by flow injection analysis. 1986

E Gaetani, and C F Laureri, and M Vitto, and L Borghi, and G F Elia, and A Novarini

A method is described for the determination of oxalate in urine using flow injection analysis and fluorimetry. Oxalate is precipitated with calcium chloride at pH 4.5, redissolved in H2SO4 and measured by flow injection analysis. The minimum detection limit is 6 mumol/l. The coefficient of variation is 7%. Results are in good accordance with normal values found with traditional oxalate analysis.
