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.

Gas chromatography is a technique used for the separation and analysis of compounds that can be vaporized without decomposition. In some cases, this technique may help to identify a compound. In preparative chromatography, gas chromatography can be used to prepare pure compounds from a mixture.
