“…Using suitable mathematical analysis, equations are derived by means of which the rate coefficient of the slow process, responsible for the sample peaks, is determined. Reversed-flow gas chromatography has been successfully used to determine gas diffusion coefficients in binary and ternary mixtures [7,8], adsorption equilibrium constants [91, molecular diameters and critical volumes of gases [10], Lennard-Jones parameters [11], activity coefficients [12,13], rates of drying of catalysts [14], rate constants, activation parameters, as well as catalytic conversions of the reactants into products for various important surface-catalysed reactions [15,16], FloryHuggins interaction parameters and solubility parameters in polymer-solvent systems [17], rate coefficients for evaporation of liquids [18], mass transfer and partition coefficients across gas-liquid and gas-solid interphases [19][20][21] Experimental set-up of the Reversed-Flow Gas Chromatography technique for studying the interactions of vinylchloride with liquid foods.…”
