本应用文献在基于使用一个简单的装置，定义两块玻璃板之间的色谱路径。可以将将经典反相气相色谱（IGC）技术（通常应用到目前的单一粉末或纤维）扩展到平面材料表面（膜材料）的研究。

     基于无限稀释的(IGC-ID)测量条件下，评估由矿物涂层改性的3个玻璃板的相互作用的可能性。而在有限浓度条件下(IGC-FC)在可以获得研究样品的相对表面积和它们的相对表面积表面能量异质性。 该研究表明，老化过程增加了相对表面积和表面涂层能量的不均匀性。

The aim of the present work is to demonstrate that, using a simple device defining a chromatographic path between 2 plates of glass, it becomes possible to extend the classical inverse gas chromatography (IGC) technique, commonly applied up to now to the sole powders or fibers, to the study of flat solid surfaces.The potential of interaction of 3 glass plates, modified by a mineral coating,  is assessed through IGC measurements,  in infinite dilution conditions,  whereas IGC at finite concentration conditions gives access to the relative surface area of the studied samples and to their surface energetic heterogeneity.  This study shows that an aging process increases both the relative surface area and the energetic heterogeneity of the surface coating.
