There are numerous methods to analyse the elements of a particular compound. One of the techniques being extensively used to analyse the components of a sample compound is gas chromatography. This is used to separate materials based on its volatilities. Once the compounds are separated, its components can be easily analysed already. This applies to chemicals which might be vaporized without a need for decomposition. Additionally, it is important in analysing the purity of a substance. This provides qualitative analysis for individual compounds in a particular sample. GC also measures giving out quantitative information.
The history of gas chromatography can be traced as early as the year 1903. It began in the work of Mikhail Semenov ich Tweet, a scientist from Russia who had used chromatography on his or her functions. A liquid to liquid chromatography was also developed in the year of 1941 and later in 1944 was the paper chromatography. These were created 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 mix of powerful and gas chromatography. These functions have started the GC or best preferred to as the gas liquid chromatography. In the year 1950, Erika Cremer had taken responsibility for the preparation for this development.
There are two phases used in the procedure. In separating the components of a chemical, a column was used. This gas chromatography column is created from a narrow metal tube. It is a filling which is a microscopic coating of liquid. This is being called the stationary phase. The sample will then be transported inside the column with the carrier gas that is usually helium, hydrogen or nitrogen. This is then referred to as the mobile or moving stage. The above procedure will use a gas separator or a gas chromatograph. This is a tool used in GC. The components will be separated through heat. This will permit the part to vaporized and distinct from other components and pass through the stationary phase. The rate and time will also be monitored throughout the process. To better understand the procedure and methods of gas chromatography, it is essential to know the different regions of the device and other peripherals.
