Comment on "systematic investigation of the sorption properties of polyurethane foams for organic vapors".

A method was devised for combining experimental partition coefficients measured at different temperatures into a single regression correlation. The proposed method described the 265 experimental air-to-polyurethane ether adsorption coefficients reported by Kamprad and Goss (Kamprad, I.; Goss, K.-U. Anal. Chem. 2007, 79, 4222-4227) to within a standard deviation of 0.084 log units, which is comparable in descriptive ability to the four temperature-specific correlations determined from a regression analysis of the experimental data at each of the temperatures studied.
