GLC determination of phenylbutazone in human plasma.
A GLC method for phenylbutazone at concentrations down to 10 ng/ml in human plasma is described. After addition of an internal standard, phenylbutazone is extracted at pH 5 into benzene. The dry extract is dissolved in benzene, and phenylbutazone is determined by GLC using a 63Ni-electron-capture detector.
