摘要： 多孔物的孔结构,一般多在干态下用氮吸附法或汞压法测定.I.Halasz等首先用反演凝胶色谱法对硅胶类多孔物作了测定获得成功.D.H.Freeman对有机交联高聚物的孔结构提出了新的数据处理方法,其它在这方而的工作亦很多。

Abstract: A new method for determining the pore structure of porous mate-rials outside the column by GPC (OGPC) has been proposed. This method can determine the pore structure of certain porous materials with a suitable solvent so that the simple equation governing elution in GPC can be applied.An equation for this method was deduced. The results of mcsurement on a sample of silica packing material were found to be satisfactory. An explanation for discrepancies in measurements on macroporous ST-DVB copolymers(which really contain also micropores) was proposed.
