前言色谱分析是先对混合物中多种组分进行分离,然后对其进行组分含量分析的过程,主要利用的原理是根据混合物中不同组分之间理化性质存在差异的特性,对混合物进行分离并测定各组分的含量或者含量比。气相色谱法的应用十分重要,不仅仅可以应用到实验四化学分析,还可以应用在环境保护和环境监测方面。环境监测是运用科学的技术手段,对其中的污染物组成成分进行定性、定量的综合分析,为环境保护提供科学的指导意见。
Preface Chromatography is the first separation of a variety of components in the mixture, and then analyze the content of the components of the process, the main principle is based on the mixture of different components of different physical and chemical properties of the characteristics of the mixture was separated And determine the content of each component or content ratio. The application of gas chromatography is very important, not only can be applied to the experimental four chemical analysis, but also can be used in environmental protection and environmental monitoring. Environmental monitoring is the use of scientific and technical means of pollutants in which the composition of a qualitative and quantitative comprehensive analysis of environmental protection to provide scientific guidance.
