We are living in a world of science and technology. There are many discoveries made every single day that make man's life easier. Without them, the world will cease to exist normally. Among many other inventions, Chromatography is one of its kind. Chromatography is technically defined as the separation of different compounds, by using mobile and stationary phases. By reading the following paragraphs, you can learn more about Capillary GC Columns, an important component of Gas Chromatography.
Chromatography and its Types: In Greek, "chromo" means "color" and graphein means "to write". Chromatography is a process that is normally used to separate, purify and test compounds. This process contains a stationary phase, which may be solid or liquid. It also contains a mobile phase, a pure solvent such as gas or water. An analyte is used in the process, which is combined with a mobile phase and pumped into the stationary phase. The mobile phase slowly moves over the stationary phase. This helps in separating the components and that is based on the solubility of the pure solvent used. Among many types of chromatography like Absorption and others, Gas Chromatography is used to separate volatile compounds. As we all know, for every process, the right components and materials are used. One such important component of GC is Capillary GC Columns. GC Columns and their uses: Two types of columns are used in chromatography: Packed and Capillary. Capillary GC Columns are especially used in Gas Chromatography. GC columns have stationary phases coated in their inner surfaces. They are not packed into the cavity like packed columns. It is mainly used to analyze the samples for any individual chemical component the compound might consist of. They provide higher sensitivity than packed chromatographic columns. Just like everybody, you might have some questions related to these columns. Let me clear a few for you. You might wonder what materials they are made up of. Traditional capillary columns were made up of glass. But, modern columns can be made up of many things like stainless steel, acrylic steel, and borosilicate glass. The basic principle of Gas chromatography is very much used in analytical chemistry to separate compounds without decomposition. They can be used to test impurities. If you are looking for a good example of their uses, you can look up their purposes in the pharmaceutical industry. They are used to test compounds for impurities there. In clinical labs, they help in determining the chemical makeup of any sample. Capillary GC Columns are created for the separation of both polar and highly polar components. If you want to know where they are sold, they can be bought from scientific gas generator system suppliers and anybody who sells apparatus used for GC or any kind of chromatography. They are one of the most vital parts of GC. Their special advantages include the high rate of separation with a proper gradient of GC oven temperature programming. If you are about to perform a GC, these Capillary columns are a must.
