Design considerations for a GC×GC system

Journal of Separation Science, 2002
Experiments in the development of two prototype interfaces for comprehensive multidimensional gas chromatography (GC x GC) have demonstrated some interesting aspects of the interface design that must be considered as researchers try to develop better interface technologies based upon thermal modulation. Studies of injection band structure from cryotrap-

Accumulating resampling (modulation) in comprehensive two‐dimensional capillary GC (GC×GC)

Journal of Separation Science, 2008
AbstractDuring each sampling period, an accumulating resampler (modulator) in comprehensive 2‐D chromatography accumulates all eluite from the first‐dimension column and reinjects the whole or a portion of the accumulated material into the second‐dimension column.

Differentiation of the six dimethoxypyrovalerone regioisomers: GC-MS, GC-MS/MS and GC-IR

Talanta, 2017
Multiple and complementary analytical methods are often necessary for the identification of a specific compound from a series of closely related structural isomers. Gas chromatography-mass spectrometry (GC-MS), gas chromatography-product ion mass spectrometry (GC-MS/MS) and gas chromatography-infrared spectroscopy (GC-IR) were used to differentiate ...

Determination of Thiosulfate in Body Fluids By GC and GC/MS

Journal of Analytical Toxicology, 1991
A simple and sensitive method to determine thiosulfate in human blood and urine was devised. Thiosulfate was first alkylated with pentafluorobenzyl bromide, with L-ascorbic acid as the stabilizer and sodium chloride as the catalyst. The alkylated thiosulfate was oxidized with iodine to obtain bis(pentafluorobenzyl)disulfide, which was then subjected to

Frequency of Gc Alleles and a Variant Gc Allele in Iceland

Human Heredity, 1980
The gene frequency for Gc1 and Gc2 in an Icelandic population was found to be 0.71 and 0.29, respectively. An electrophoretic variant similar to Gc Norway was detected in 5 individuals of the same family. A pedigree of 14 family members, including two spouses, is presented.
