title: Gas-liquid chromatographic method for the measurement of methyl urea in blood and urine.
abstract: A technique for the measurement of methyl urea in biological fluids is described based upon gas-liquid chromatography of its trifluoroacetyl derivative. The method requires 10 ml of either blood or urine and is capable of measuring methyl urea at concentrations of less than 5 mg/l.
