“…The carrier gas hold up time in the column was determined by injecting a small amount of methane with the sorbate. Corrected net retention volumes, VN, and sorbate partial pressures, p , corresponding to the maxima of elution peaks of different sizes were plotted so that q , the surface concentration of adsorbate (mol g-I) would be obtained as a function ofp by integrating the plot in the usual way (8)(9)(10)(12)(13)(14).…”

Gas–solid chromatography is shown to provide a method for measuring the specific surface area of non-porous particulate mineral or oxide samples in the range 0.005 to 0.5 m2 g−1 with precision as high as ±10%. Mesitylene is a convenient sorbate and was found to occupy an area of 71 ± 5 Å2 per molecule on silicate surfaces, by calibration with glass particles having well defined surface geometries. The rather low values obtained for the C parameter, when fitting retention volume data to the BET equation, suggest that the area occupied by mesitylene may be affected by the surface on which it is adsorbed. Hydrocarbon contaminants are a major interference. No specialized instrumentation is required.

“…Inverse chromatography has been used to measure the surface areas of inorganic salts (11) and polymer fibers (8,9,(12)(13)(14) using large probe molecules near room temperature. Thibault and co-workers (15) measured low specific surface areas of metals using methane as a probe molecule at liquid nitrogen temperatures.…”

“…Surface energy and acid-base characteristics, obtained from IGC, will, therefore, describe the performance of these surface fractions and not necessarily the performance of the surface as a whole. More detailed descriptions of solid surfaces would necessitate the determination of adsorption isotherms of site energy distributions [73,116,[138][139][140][141][142]. In many instances, however, the dominant surface interactions of a solid will be those involving the high-energy sites [11,25].…”

The properties of a polymeric system are a consequence of the interactions that occur between the various components of these complex systems. These components may vary significantly in terms of chemical nature (e.g. organic/inorganic), physical properties (e.g. particle size, surface area, molecular weight), structural characteristics and proportion in the formulations composition. This review paper addresses the major approaches in use regarding the analysis of the interactions that occur between the polymeric system components and the use of such approaches in the interpretation of the chemical, physical and thermodynamic properties of these systems. Special attention is given to the technique of inverse gas chromatography.A case study is presented, where use was made of inverse gas chromatography to characterize thermodynamically the surface of the major components of pigmented PC/PBT blends. The concept of Lewis acidity/basicity was used in the interpretation of the intermolecular interactions nature and potential in these blends, as encountered in phase separation and phase preferences phenomena and as expressed in the morphology, the physical and the mechanical properties of these commercially important composites. #
