There are numerous approaches to analyse the elements of a specific compound. Among the techniques being commonly utilized to analyse the elements of a sample chemical is gas chromatography. This is used to separate substances based on its own volatilities. Once the chemicals are separated, its elements can be readily analysed already. This applies to compounds which may be vaporized without a need for decomposition. Additionally, it is important in testing the purity of a material. This provides qualitative analysis for individual compounds in a specific sample. GC also steps giving out quantitative information.

History of Gas Chromatography

The history of gas chromatography can be traced as early as the year 1903. It started in the work of Mikhail Semenov ich Tweet, a scientist from Russia who had used chromatography on his functions. A liquid to liquid chromatography was also developed in the year of 1941 and later in 1944 was the paper chromatography. These were developed by Archer John Porter Martin. Martin got a Nobel Prize for his liquid to liquid chromatography. In the year 1947, Fritz Before, a graduate student from Germany, made the blend of strong and gas chromatography. These functions have begun the GC or best preferred to as the gas liquid chromatography. In the year 1950, Erika Cremer had taken responsibility for the groundwork for this development.

Procedure for Gas Chromatography

There are two stages used in the procedure. In separating the elements of a compound, a column has been used. This column is produced from a narrow metal tube. It has a filling that is a microscopic coating of liquid. This is being called the stationary phase. The sample will then be transported within the pillar using the carrier gas that is usually helium, nitrogen or hydrogen. This is then known as the cellular or moving stage. The above procedure will use a gas separator or a gas chromatograph. This is a tool used in GC. The elements will be separated through warmth. This will allow the part to vaporized and different from other parts and pass through the stationary phase. The speed and time will also be monitored throughout the procedure. To better understand the procedure and methods of gas chromatography, it is crucial to know the different areas of the instrument and other peripherals.
