Abstract:
A gas liquid chromatographic method for determination of catecholamines in small sample is described. The method involves homogenization of biological material into 0,1 M formic acid 5 mM ascorbic acid and subsequent conversion in their trimethylsilyl derivatives with BSA reagent and determined on 3% OV-1 column in a isothermal condition at 220 degrees C with the cromatograph equipped with hydrogen flame ionization. With respect to specificity, reproducibility and recovery, the results were satisfactory.
