相平衡原理适用于测定收集在活性炭上的有机化合物的解吸效率。该方法依赖于解吸溶剂-吸附剂基质中有机物的吸附相和溶液相之间存在真正的平衡分布。通过考虑吸附剂-溶剂比和分析时的平衡温度的变化的影响，获得了改进的和更一致的解吸效率。该技术还可以提供吸附剂表面上的吸附物的相互作用或反应的早期检测。
The principle of phase equilibrium is applied to the determination of desorption efficiencies of organic compounds collected on activated charcoal. The method depends on the existance of a true equilibrium distribution between the adsorbed and solution phases of organics in the desorption solvent--adsorbent matrix. Improved and more consistant desorption efficiencies are obtained by considering the effects of variations in the adsorbent--solvent ratio and equilibrium temperature at time of analysis. The technique may also provide early detection of interaction or reaction of the sorbate on the adsorbent surface.
