There are various ways in which chemists and analysts would analyze a compound. One of the most common ways of doing so is the gas chromatograph process. In this process, the compound is to be separated for analysis and perhaps this will help to understand whether the sample is pure or not. This analysis or this kind of process is quite useful in the food and beverage industry. It also plays a key role in the mining and oil and gas industries. There are several benefits of this process and they are given hereunder.

The role of chromatography in physicochemical characterisation

• Chromatography has been a fundamental technique used for chemical separation. Specifically, column chromatography, typically taught in introductory organic chemistry laboratories. This situation runs contrary to the principles of responsible chemical and waste management emphasized by the green chemistry movement. • Chromatographic techniques have significant role in natural products chemistry as well as contribute dramatically in the discovery of novel and innovative compounds of pharmaceutical and biomedical importance. • This study focused on step-by-step visual demonstration of fractionation and isolation of biologically active plant secondary metabolites using column-chromatographic techniques.
