Rapid gas-liquid chromatographic method for plasma verapamil level determination.
Verapamil is a newly marketed antiarrhythmic drug. It has a significant presystemic elimination when administered orally and, therefore, intravenous therapy is often recommended. Optimum therapeutic effect is obtained when verapamil plasma concentrations are between 100 and 400 ng/ml. Several chromatographic procedures for the determination of verapamil in biological fluids have been described ...

متن کاملGas-liquid chromatographic determination
A method for the determination of total bile acids in human feces that is suitable for routine application is described and discussed. Bile acids are extracted from freezedried feces with acetic acid and toluene, in the presence of the i?ternal standard 23-nordeoxycholic acid. After saponification of the extract, bile acids and the internal standard are methylated and converted by mild chromic ...
متن کامل"a gas chromatographic method for the determination of individual free fatty acids in serum"
serum fatty acids on 30 healthy lranian women were detemined by a gas chromatographic method. oleic and stearic acids were used as standards. the mean values were myristic acid 5. 7% , palmitic acid 43% , palmitoleic acid 5.3% , stearic acid 8% , oleic acid 21. 3% and linleic acid 16.4% of total fatty acid serum contents.
متن کاملGas-chromatographic determination of cholesterol in serum: candidate reference method.
We present a candidate Reference Method for determination of total cholesterol in serum. The method is based on high-resolution capillary gas chromatography, and we took special precautions with respect to weighing, calibration, and chromatographic peak integration. Analytical recovery of added cholesterol was essentially complete (99.99%, SD 0.48%) and reproducibility was excellent (total CV 0...
