Separation of triglycerides by gas-liquid chromatography.
The parameters affecting the separation and quantification of triglycerides by gas-liquid chromatography have been investigated with the use of QF-1 and SE-30 as stationary phases and a flame ionization detector. The isothermal characteristics of a wide variety of triglycerides (carbon number 6 to 60) on both columns show that long retention volume is directly proportional to carbon number and ...
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 کاملChromatographic separation procedures: gas chromatography with Cobra4
Principle Chromatographic procedures allow a separation of substance mixtures with the aid of a stationary separating phase and a mobile phase. In gas chromatography the mobile phase is a gas. The mobile phase, to which the mixture to be separated is added, transports the substance mixture through the separation column at a constant flow rate. Interactions occur between the mobile phase and the...
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 کاملSeparation of light hydrocarbons by gas chromatography using serpentine as stationary phase
The application of serpentine ore (brownish colour) as a stationary phase for the separation of hydrocarbons by gassolid chromatography has been tested. Separation of methane, ethane, propane, n-butane, iso-butane and acetylene has been accomplished at room temperature (25°C). The separated components were detected with a flame ionization detector. The peaks of isobutane and n-butane were rathe...
