Gas chromatography is one of the specific techniques in the chemical industry to separate the set of volatiles compounds that may contain a sample. This is a technique that has marked a turning point in analytical procedures in this industrial area.
This procedure, in its analytical side, allows analyzing the compounds present in a sample, but also purify a mixture, which has multiple applications.
The procedure followed in gas chromatography consists in the volatilization of the sample that is transported through the chromatography column, (one coil) through a gas. In this process, the compounds are separated depending on their level of volatility (tendency of a substance to pass into the vapour phase) and its affinity toward a fixed position, this is called the stationary phase.In fact, the essential part of a gas chromatograph consists of a long thin coil that has a liquid primer on their walls (stationary phase) to mark the point of volatilization.
Given the high degree of mechanization and accuracy of this procedure, instruments for the manufacture of gas chromatographs require precision materials and certified components.
In these manufacturing processes fit the technical specifications and features of the product welded and redrawn stainless steel tube in coil, in grade AISI-316 ANNEALED, with manufacturing tolerances of +/- 0.05 mm.
The fundamental basis of its quality is an alloy of stainless steel, iron and a minimum of 10.5% chromium. In fact, the alloy AISI-316is a stainless steel with austenitic composition and with face-centered cubic structures. Its features are obtained by forming an invisible and adherent chromium oxide film. Its a hight quality product.And although it is exposed here the application features of the welded and redrawn stailness tube in coil, in grade AISI 316 ANNEALED for gas chromatographs, they are also applied for the aviation industry, railway, naval or petrochemical equipments among others.
Chromatography applications are analytical such as industrial. Accordingly, on the one hand it enables purifying a compound from the separation of its components and subsequently they can be used; and on the other hand, it will allow to separate and analyze components of a complex sample and thus it makes possible to identify and quantify the amounts in which these components are present in the original sample, however small it may be.Gas chromatography, although was born as a procedure for analytical and chemical industry, nowadays it is applied in large branches of science
