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.
متن کاملApplication of Pyrolysis Gas Chromatography in Forensic Science.
In this review the range of evidentiary materials that may be successfully examined by pyrolysis gas chromatography is emphasized. Initial sections briefly discuss the main types of commercially available pyrolyzers, i.e., inductively heated devices (Curie point), those employing resistive heating, and furnace pyrolyzers. Sample introduction methods and the effects of various pyrolysis paramete...
متن کاملDetermination 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...
متن کاملDifferentiation 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...
متن کاملRecent trends and developments in pyrolysis-gas chromatography.
Pyrolysis-gas chromatography (Py-GC) has become well established as a simple, quick and reliable analytical technique for a range of applications including the analysis of polymeric materials. Recent developments in Py-GC technology and instrumentation include laser pyrolysis and non-discriminating pyrolysis. Progress has also been made in the detection of low-level polymer additives with the u...
