过量表面功（即吸附量和化学势变化与吸附量的乘积）的绘图得出单层容量处的最小值，该单层容量归因于第一吸附分子层。获得的第二个参数是吸附开始时化学势的变化。积分评估给出了线性化形式，可以从斜率和截距找到这两个参数。该模型可用于气相和液相的吸附。在精度和有效性范围方面，该模型是对其他方法尤其是BET方法的改进。
A plot of the excess surface work that is the product of the adsorbed amount and the change in chemical potential versus the adsorbed amount yields a minimum at the monolayer capacity which is attributed to the first adsorbed molecular layer. The second parameter obtained is the change in chemical potential where adsorption sets in. An integral evaluation gives a linearized form from which both parameters can be found from slope and intercept. The model can be used for adsorption from gas and liquid phases. Regarding the precision and range of validity, the model is an improvement on other methods, especially the BET method.
