A Simple Gas Chromatographic Method for the Measurement of Dichloroacetic Acid in Plasma or Urine

Abstract
A method was developed for measurement of dichloracetic acid in plasma [human] or urine. The procedure is based on derivatization of dicloroacetic acid with methanol-boron trifluoride, extraction of the resulting methyl ester and gas chromatography. The method has good accuracy and precision, and can be used to determine concentrations as low as 0.04 .mu.g/ml.
