层析技术在近几年来发展极其迅速。国內已陆續发表了很多这方面的綜述性文章,諸如薄层层析、离子交換纤維亲层析、气相层析、离心层析、凝胶过滤和盐析层析等。最近在药物分离和鑑定中,某些新的层析技术已逐漸取得广泛应用。本文拟在这方面作一扼要介紹。聚酰胺吸附剂聚酰胺(Polyamide)是一种具有选择性的 Chromatography technology has developed extremely rapidly in recent years. A number of review articles in this area have been published in China, such as thin layer chromatography, ion exchange fiber affinity chromatography, gas chromatography, centrifugal chromatography, gel filtration, and salting-out chromatography. Recently, in the separation and identification of drugs, some new chromatography techniques have gradually become widely used. This article intends to give a brief introduction in this regard. Polyamide adsorbent Polyamide is a selective
