Gas chromatographic behavior of cotton fiber, as column stationary phase, was investigated by injecting water as probe. The retention volume decreased with temperature over a range of 70-120°C, while it decreased with increasing the probe size until a point of inflexion then increased linearly with larger sample size. Carrier gas flow rate did not affect the amount of sorption at 90°C. Though the amount of sorption by inverse gas chromatography was slightly smaller than that by static method, a reasonable agreement of BET constants suggested that inverse gas chromatography was useful for determination of adsorption isotherm even below Tg BET monolayer capacity corresponded to the amount of sorption at a point of inflexion with regard to flow rate of 20ml/min and 40ml/min, adsorption monolayer was formed around this point and multilayer adsorption occurred at higher probe concentration.
