目前,纸层析与薄层层析是微量物质分析分离中最常用的技术。近二十年来,尽管有关纸层析的报道比薄层层析相应减少,也有人预言薄层层析将会取代纸层析,但也有学者持有不同看法,认为纸层析在使用上既经济又方便的特色不能抹煞,并指出它很有发展前途。其中之一就是将纸层析与薄层层析二者结合起来,含硅胶的层析滤纸(以下简称硅胶纸)的应用就
At present, paper chromatography and thin layer chromatography are the most commonly used techniques for the separation of trace substances. In the recent two decades, although paper reports on paper chromatography have decreased correspondingly to those on thin-layer chromatography, some have predicted that thin-layer chromatography will replace paper-based chromatography. However, some scholars hold different opinions that paper-based chromatography Economical and convenient features can not be ignored, and pointed out that it has great prospects for development. One of them is the combination of paper chromatography and thin layer chromatography. The application of chromatographic filter paper containing silica gel (hereinafter referred to as silica gel paper)
