TL;DR: Support-bonded silicones, such as (C18H37SiO3/2)n on various types of Chromosorb, can be used to trap organic vapors from the atmosphere and be extracted and the concentrated extracts analyzed by various analytical techniques.

TL;DR: In this article, three typical silicone monomers have been coated on Chromosorb G and W supports and polymerized in gas chromatographic columns, using chemistry developed for support-bonded polymers.

TL;DR: The N-trifluoroacetyl n -butyl ester/gas-liquid chromatographic method has been shown to give recoveries greater than 80% when samples containing 5 ng of each of seventeen amino acids were taken through the total derivatization and chromatography, thus showing that losses due to adsorptive and substrate-derivative interactions were minimal.

TL;DR: In this paper, two types of support-bonded silicones, (C18H37SiO 3 2 )n and [(CH3)2SiO]n), were chemically bonded to Chromosorb of the W and G varieties in a fluidized bed polymerization.

TL;DR: In this paper, it has been shown that the response of the detector is proportional to the amount of hetero-element introduced; however, other authors disagreed and suggested that the proportionality of the response depends on the choice of a suitable standard and proper chromatographic conditions.

TL;DR: In this article, a normal flame ionization detector has been modified such that the flame burns in contact with liquid indium and the emission from indium or its halides can be detected by a spectrometer or a filter-photomultiplier combination.

TL;DR: A typical pellet-type alkali flame detector was monitored photometrically as discussed by the authors, and its predominant mode of response is negative, i.e. alkali emission decreases when gas chromatographic effluents are burned in the flame.
