Determination of Alkyltrimethylammonium Chlorides in Cosmetics by Injection Port Pyrolysis Gas Chromatography.

Determination of sulfonylureas and metabolites by pyrolysis gas chromatography.

Various sulfonylurea derivatives are widely used to treat some types of diabetes. Although thousands of different compounds have been shown to possess some hypoglycemic activity (1), only a few are used therapeutically. The dose required to achieve an effective plasma concentration of sulfonylurea varies from person to person and even from time to time in the same person (2, 3). Some of the pro...

Determination of dihydroqinghaosu in blood by pyrolysis gas chromatography/mass spectrometry.

Differentiation of selected Enterobacteriaceae by pyrolysis-gas-liquid chromatography.

Pyrolysis-gas-liquid chromatography was used to differentiate selected species of Enterobacteriaceae. Individual cultures of Salmonella typhi, Hafnia alvei, and Proteus vulgaris, and 12 strains of Yersinia enterocolitica were grown in nutrient broth. After harvest and lyophilization, the bacterial samples were pyrolyzed at 900 degrees C, and their volatile fractions were separated on a 50-m cap...

Paints and Coatings: Pyrolysis: Gas Chromatography

In this review, the principles behind, and the utility of, fractionation of subcellular organelles by centrifugal techniques have been explored. Common methods used, and a review of the advantages and disadvantages of certain experimental tools (centrifuges, rotors, and aqueous media used for fractionation) were also reviewed and tables and graphs useful for designing protocols were also provided.

Determination of halocarbons in drinking water by direct aqueous injection gas chromatography.
