以ＰＥＧ２０Ｍ为代表研究了石英毛细管柱气液色谱保留过程，提出了利用毛细管柱测定分配和吸附常数的公式，并测定了９个温度下的分配和吸附常数。计算了８０℃和１２０℃下４支不同液膜厚度柱上吸附对保留的贡献。结果表明，在薄液膜的柱子上界面吸附对保留具有重要贡献；温度升高可以降低弱极性化合物（如正构烷烃和饱和醚）吸附对保留的贡献，但对其它化合物影响不明显。验证了正构烷烃、２－酮系列和正构伯醇的吸附常数的碳数规律。由于溶质从界面向体相转移对能量并不是一个很有利的过程，因而产生了有意义的界面吸附；吸附的强弱与溶质的沸点和溶质在体相的作用大小有关，在此基础上得出了吸附常数与分配常数和沸点的关系。通过吸附和分配常数与温度的关系内插或外推计算各化合物在相应沸点时的平衡常数，结果表明二者间仅相差一个常数。
Taking PEG20M as the representative, the gas-liquid chromatographic retention of quartz capillary column was studied. The formula for determining the partitioning and adsorption constant by capillary column was proposed. The distribution and adsorption constants were also determined at nine temperatures. The contribution of adsorption on four different liquid film thickness columns at 80 ℃ and 120 ℃ was calculated. The results show that the adsorption on the thin liquid membrane column has important contribution to the retention. The increase of temperature can reduce the contribution of the adsorption of the weak polar compounds (such as n-paraffins and saturated ethers) to the reservoirs, but the influence on other compounds is not obvious. The carbon number regularity of the adsorption constants of normal paraffins, 2-keto series and normal primary alcohols was verified. Since the transfer of solute from the interface to the bulk phase is not a very favorable process for energy, it results in a meaningful adsorption of the interface; the strength of the adsorption depends on the boiling point of the solute and on the size of the solute in the bulk phase The relationship between the adsorption constant and the distribution constant and the boiling point is shown. The equilibrium constant of each compound at the corresponding boiling point was calculated by interpolation or extrapolation of the relationship between constant and temperature by adsorption and distribution. The results showed that there was only a constant difference between them.
