Popis:	The partial solubility parameters of cellulose and AKD (Alkylketene dimer) treated paper were determined by inverse gas chromatography. The Snyder/Karger-Hansen interaction model was used, where -ΔEA = Viδl d + δl pδj p + δj h δj h). The adsorption internal energies of a series of n-alkanes and five polar probes were measured. From the ΔEA values of n-decane, acetone and THF, which give the largest normalized determinant M(n), the partial solubility parameters of the stationary phases were calculated. The partial solubility parameters of cellulose were: δd = 8027; δp = 8.00; δh = 13.88; δt = 18.03 cal½/cm3/2 AKD treated paper gave δd = 8.10, δp = 12.35, δh = 7.96, and δt = 16.78 cal½/cm3/2.
