层析纸主要成分为多羟基纤维,具有载体和固定相的双重作用。价廉易得,方法简便,容易分离、洗脱、回收率较高,为生物碱、氨基酸等常用的检测方法和仪器分析的辅助手段。但有着层析时间长、分离效果和机械强度较差等缺点。为了扬长避短而进行了如下改进。一、层析纸的预处理层析纸要求纹理细致、均匀、平整无折
The main component of the chromatographic paper is polyhydroxy fiber, which has the dual role of carrier and stationary phase. The method is simple and inexpensive, the method is simple, the method is easy to separate, elute and the recovery rate is high. The method is commonly used as an alkaloid and amino acid detection method and an auxiliary method for analyzing instruments. But with a long time of chromatography, the separation effect and poor mechanical strength and other shortcomings. In order to avoid weaknesses and made the following improvements. First, the pretreatment of chromatography paper chromatography paper requires detailed texture, uniform, smooth formation
