title: Determination of papaverine in blood samples by gas-liquid chromatography and mass fragmentography.
abstract: The measurement of papaverine in blood samples by using either a glass capillary column with a flame-ionization detector or a packed column with mass fragmentographic detection is described. The two methods permit the determination of the normal range of concentrations of papaverine in blood (2-500 ng/ml). Owing to its high specificity, mass fragmentography is greatly superior to capillary chromatography, which is sometimes subject to interferences by solvent impurities.
