Inverse gas chromatography in characterization of surface
Inverse gas chromatography (IGC) has become an accurate, reliable and fast method for the physicochemical characterization of polymers and their blends, fibers, modified silica and other surfaces, surfactants, as well as, commercial stationary phases and their mixtures and petroleum pitches, heavy residues of oil distillation. Possibilities of application of inverse gas chromatography in the ch...
متن کاملParticulate Characterization: Inverse Gas Chromatography
Inverse gas chromatography (IGC) represents a unique reRnement of a classic chromatographic method in which an unknown solid material such as a powder, Rbre or Rlm may be characterized. By reversing the traditional role of unknown mobile phases and known reference stationary phases, the gas}solid chromatographic retention processes may be used to characterize an unknown particulate sample by el...
متن کامل1-Butyl-3-Methylimidazolium Bromide Promoted Selectively Oxidation of Sulfur Compounds by NaBrO3
1-Butyl-3-methylimidazolium bromide ([bmim]Br) as an ionic liquid promoted selectively oxidation of aliphatic and aromatic sulfides to the corresponding sulfoxides and the oxidative coupling of thiols to disulfides by NaBrO3 in excellent yields under neutral conditions.
متن کاملCharacterization of Glass Transition Temperature and Surface Energy of Bituminous Binders by Inverse Gas Chromatography
Inverse gas chromatography (IGC) was used to characterize two bituminous binders (A and B) of different origin. Glass transition temperatures (Tg) were determined by constructing van’t Hoff plots using n-pentane probes in a temperature range between -50 °C and +120 °C. Tg values were specified using the first deviations from linearity observed in the adsorption zone of the plots. A 6 °C differe...
متن کاملDetermination of 3,6-dichloropicolinic acid residues in soil by gas chromatography of the 1-butyl ester.
Since 3,6-dichloropicolinic acid is simil8r to picloram, the method developed previously for picloram by McKone and Cotterill (1974) was examinedo This method~ like that of Pik and Hodgson, uses diazomethane for methylationo However~ the methyl ester of 3 87 acid is sufficiently volatile for losses fo occur during the final concentration stepo This report shows how tbe difficulty tan be overcom...
