摘要

气相色谱法(GC)在气相色谱法中,样品的成分溶解在溶剂中并汽化,通过将样品分布在两相之间来分离分析物:质谱(固定相和流动相)是一种常用的分析技术,作为许多研究和工业研究设施的一部分,用于质量控制,此外,鉴别和定量混合物中的成分质谱是一种先进而强大的定性和定量分析技术。这里介绍的火焰电离探测器非常容易构造,非常敏感,并且很容易看到演示目的。原子发射检测(AED)是一种灵敏、选择性的气相色谱(GC)检测技术,可提供元素特异性信息。本文重点介绍了气相色谱的仪器、色谱柱、检测器、应用、优缺点。气相色谱法是一种根据化合物极性从复杂混合物中分离化合物的分析工具。分离仅对挥发性或可在使用衍生化剂对化合物进行衍生化时使其挥发的化合物实现。

A Brief Review on Gas Chromatography
Gas Chromatography (GC In gas chromatography, the components of a sample are dissolved in a solvent and vaporized in order to separate the analytes by distributing the sample between two phases: a stationary phase and a mobile phase) is a normally utilized analytic technique as a part of numerous research and industrial research facilities for quality control and in addition identification and quantitation of components in a mixture Mass spectroscopy is an advanced and powerful technique for qualitative and quantitative analysis. . The flame ionization detector presented here is very easy to construct, extremely sensitive, and readily visible for demonstration purposes. Atomic emission detection (AED) is a sensitive as well as a selective detection technique for gas chromatography (GC) and provides element-specific information the paper focused on Instrumentation, Column, Detector, Application, Advantages and Disadvantages in gas chromatography. Gas chromatography is an analytical tool for the separation of compounds in complex mixtures based on the polarity of compounds. Separation is achieved only for compounds that are volatile or that can be made volatile on derivatization of the compound using derivatizing agents.
