TL;DR: Carbowax 20M was coated on Chromosorb W, heat-treated at 280°, and exhaustively extracted as mentioned in this paper, with the remaining support performed chromatographically in a manner similar to highly efficient, well deactivated gas.

TL;DR: Silicones can be synthesized from a variety of pure or mixed monomers on and chemically bonded to silicicic surfaces as discussed by the authors, typically to chromatographic supports The resulting materials are non-extractable, thermally stable coatings which perform well in GLC and can be used for some of the more demanding types of analysis

TL;DR: Citric and nitrilotriacetic acids can be determined at the 1–10,000 p.p.b. 1 levels in aqueous systems ranging from tap water to sewage effluents by use of anion-exchange clean-up, derivatization with butanol—HCl and gas chromatography.

TL;DR: In this article, a multistage process was described to produce silicones polymerized on, and chemically bonded to, chromatographic supports, and the resulting phases were characterized by gas liquid chromatography in terms of column bleed, solute retention and resolution; by liquid phase extractability, by thermogravimetric analysis, and C, H analysis.
