What is a Gas chromatograph?

A gas chromatograph is a device used for qualitative and quantitative analysis of compounds that are easily vaporized. It is often abbreviated as gas chromatograph, and is sometimes abbreviated as GC from the abbreviation of Gas Chromatograph, which is an English notation. Along with high performance liquid chromatograph, it is a very famous analysis method. The principle is that after the sample is vaporized, each component is separated to determine the type and content of the compound. The biggest merit is that it can analyze very low concentrations of volatile components. Currently, he is active in a wide range of fields such as pharmaceuticals, foods, and the chemical industry, contributing to the basics and development of science and technology. In addition, there is gas chromatography as a word very similar to gas chromatograph, and both expressions are often confused, but the former (gas chromatograph) means ""experimental equipment"" and the latter (gas chromatography) means ""gas chromatograph"". The meaning is different because it means ""separation operation used".

Application of Gas chromatograph

Gas chromatographs are used for the purpose of separating and analyzing compounds in fields such as pharmaceuticals, foods, and chemistry. For example, it has a wide range of uses such as measurement of harmful substance concentration and component analysis of gas generated in the device. However, be aware that not all compounds can be analyzed. Due to its principle, gas chromatography cannot generally analyze non-volatile compounds with a boiling point of 400 ° C or higher or unstable compounds that decompose at high temperatures. Inorganic metals, ions, and highly adsorptive compounds are also difficult to analyze for the same reason, so they must be confirmed before analysis.
