GLC determination of guaiacol glyceryl ether in blood.

it was difficult to obtain directly in a single experiment films of exactly 0.1-mm. thickness, several films were selected so that the thickness of each film might be distributed in a range from 0.05 to 0.4 mm. and the respective water vapor permeability was measured at various humidity conditions. Plotting the relationship between permeation resistance (l/Q) and film thickness (I) gave a strai...

Quantitative Determination of Dihydrostreptomycin by Periodate Oxidation.

Dihydrostreptomycin is produced commercially by the catalytic hydrogenation of streptomycin. The reaction involves the reduction of the aldehyde group in the streptose moiety of the streptomycin molecule to the corresponding primary carbinol group as evidenced by the failure of dihydrostreptomycin to react with carbonyl reagents or with alkali to produce maltol. As there are no chemical methods...

Gas-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 ...

Gas-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...

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 ...
