Inverse gas chromatography (IGC) at infinite dilution was applied to evaluate the surface properties of sorbents and the effect of different carrier gas humidity. They were stored in different environmental humidity - 29%, 40%, and 80%. The dispersive components of the surface free energy of the zeolites and perlite were determined by Schulz-Lavielle method, whereas their tendency to undergo specific interactions was estimated basing on the electron donor-acceptor approach presented by Flour and Papirer. Surface parameters were used to monitor the changes of the properties caused by the humidity of the storage environment as well as of RH of carrier gas. The increase of humidity of storage environment caused a decrease of sorbents surface activity and increase the ability to specific interaction.
反气相色谱（IGC）在无限稀释条件下被应用于评估吸附剂的表面性质和不同载气湿度的影响。它们被储存在不同的环境湿度下-29%、40%和 80%。沸石和珍珠岩的表面自由能的色散分量是由 Schulz-Lavielle 方法测定的，而它们发生特定相互作用的趋势则是基于 Flour 和 Papirer 提出的电子供体-受体方法来估计的。表面参数被用于监测由储存环境的湿度以及载气的相对湿度引起的性质变化。储存环境湿度的增加导致吸附剂表面活性的降低和特定相互作用能力的增加。
