随着层析理论的发展和高效填充剂的发现,使薄层色谱分析有了进一步提高。高效薄层色谱分析法是近十年来发展起来的一种微量分析手段,它的优点是:点样量少,展开距离短,分辨力高,检出限度低(一般可达微微克)。七十年代后期由于高效吸附剂的出现,促进了高效液相色谱的迅速发展,并又为薄层层析技术的提高提供了条件,使薄层层析作为一种分析手段,配合各
With the development of chromatography theory and the discovery of efficient fillers, TLC analysis has been further improved. High-performance thin-layer chromatography is a trace analysis method developed in recent ten years. Its advantages are: less sample, short distance, high resolution and low detection limit (generally up to pico grams). The late seventy’s due to the emergence of highly effective adsorbents to promote the rapid development of high performance liquid chromatography, but also for the improvement of thin-layer chromatography provides the conditions for thin-layer chromatography as an analytical tool, with the
