Since the boiling point of undecane ( 196 �C ) is well known, it may be used as a comparison for retention times in a gas chromatograph for molecules whose structure has been freshly elucidated.

It has also been argued that the Labeled Release ( LR ) experiment detected so few metabolising organisms in the Martian soil, that it would have been impossible for the gas chromatograph to detect them.
43.
Compare that with the first episode of " CSI : Miami, " in wHicx co-star Kim Delaney used a Thermo Finnegan Trace DSQ Gas Chromatograph Mass Spectrometer to analyze a hair from an airplane crash victim.

After clearing the gas chromatograph syringe to equalize the gas concentration within the package with the sampling tubes, gas samples were withdrawn from the multipack via a syringe and analyzed on a gas chromatograph ( GC ).

More recently, the portable gas chromatograph, " OralChroma " has been recommended in the diagnosis of halitosis, as the Halimeter does not detect dimethyl sulfide, which is thought by some to be elevated in extraoral causes of halitosis.
47.
The assumption by the scientists was that if seaborgium reacts with these substances the way molybdenum and tungsten do, the similarity should become evident from the behavior of the reaction products passing through a device called a gas chromatograph.

June 6, 2011 Dr . Arpad Vass of the Oak Ridge National Laboratory describes using a gas chromatograph mass spectrometer to find signs of human decomposition and a high level of chloroform in the trunk of Casey's car.
49.
But other experts in the analysis of explosives and blast residue say that the usual tool applied to such problems, a gas chromatograph coupled with a mass spectrometer, can easily detect and identify even the traces of chemicals present in a fingerprint.
50.
This laboratory in conjunction with several chemists, and the Department of inherited rare diseases in the medical school made significant inroads in identifying inherited rare diseases from the gas chromatograph, mass spectrometer data generated from blood and urine samples of sick children.
