Sulfur Compounds: Gas Chromatography

(tetrahydrofuran) at 703C for 16 h. The ester residue is then converted to a 6,6-dideuteriohexose residue, the O-methyl ethers of which are easily distinguishable by GC-MS of the derived alditol acetates. An alternative to acid hydrolysis that is applicable to most polysaccharides and glycoconjugates, including those containing acid-labile residues or glycosidic linkages resistant to hydrolysis...

Atmospheric Analysis: Gas Chromatography

The determination of both naturally produced and anthropogenic organic species in the atmosphere is a key area in atmospheric chemistry research. Nearest to the earth’s surface, within the boundary layer of the troposphere, the determination of hydrocarbon species is important because of their ability to react rapidly with NOx in the presence of sunlight to form photochemical smog. At the other...
