当液体用作载体相时,相应的反色谱技术称为反液相色谱法(ILC)。
该技术提供了一种动态的方法来研究吸附各种分子探针在粉末,颗粒上的液体介质或纤维。 

低分子量分子,或者大分子或表面活性剂都可以用作探针。
获得的信息是:
•吸附等温线,
•解吸等温线,
•不可逆吸附探针的数量。


When a liquid is used as carrier phase, the corresponding . Inverse Chromatography technique is called Inverse Liquid
Chromatography (ILC).

This technique offers a dynamic way, to study the adsorption in liquid media of various molecular probes onto powders, particles or fibers. Low molecular weight molecules, but also macromolecules or surfactants could be used as probes.
The obtained informations are:
•adsorption isotherms,
•desorption isotherms,
•the amount of irreversible adsorbed probes.


反液相色谱(ILC)是研究固/液相互作用的技术,专门用于基于标准液体的溶质吸附等温线的测定设备。 色谱柱装有要表征的材料,并且待吸附的探针分子以高浓度溶解在流动相中。


Inverse Liquid Chromatography (ILC) is a technique for studying solid/liquid interaction and most specifically for the determination of solute adsorption isotherm based on the use of standard liquid chromatography equipment . The column is packed with the material to be characterized, and the probe molecule to be adsorbed is dissolved in the mobile phase at high concentration.
