Abstract
The previous paper in this series(1) dealt with the factors affecting the desorption efficiency. This paper continues by attempting to deal with the problems arising from the factors and interactions demonstrated. In particular, a mathematical treatment for linearizing the desorption efficiency-loading relationship is derived. The method successfully linearizes experimental data for 2-ethoxyethyl acetate and data in the literature for acetone. Data for the dependency of the desorption efficiency on desorption volume at constant loading for biphenyl is shown to fit the theoretical equation quite well. Finally, a method is described which eliminates the dependence of the desorption efficiency on the presence of other compounds for mixtures of polar compounds.
