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...

15 صفحه اولCharacterization 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 کاملTotal Surface Energy Distributions Determined Using Inverse Gas Chromatography at Finite Dilution for Understanding the De-agglomeration of Lactose Powders
Purpose: This study determined total surface energy distributions using an Inverse Gas Chromatography (IGC) to understand the de-agglomeration of fine lactose powders commonly used in dry powder inhaler formulations. Methods: The particle size distribution (PSD) of two lactose samples, Lactohale 300 (Lac A) and micronized lactose (Lac B), were determined by laser diffraction in liquid media, an...
