气相层析法作为高效、快速、灵敏的现代分离分析技术,已广泛应用于生产和科研;气相层析的理论也在实践中不断丰富、发展和提高。但是,在气相层析鉴定技术方面,尚未获得具有决定意义的突破。目前,欧、美、日、苏等国大多致力于对Kovats保留指数的探讨,希望从中最后启开层析鉴定之门。 As an efficient, rapid and sensitive modern separation and analysis technique, gas chromatography has been widely used in production and research. The theory of gas chromatography has been continuously enriched, developed and improved in practice. However, breakthroughs of decisive significance have not yet been achieved in the identification of gas chromatography techniques. At present, most countries in Europe, the United States, Japan, and the Soviet Union are devoted to discussing the Kovats Retention Index, hoping to finally open the door of the chromatography identification.
