Gas Chromatographs - the Intricacies and Peculiarities

1. Gas Chromatographs - the Intricacies and Peculiarities Gas chromatography - a technique for studying complex mixtures by separation of volatiles. In this case, an inert gas (carrier gas) serves as a mobile phase, which interacts with the stationary phase. The inert gas may be helium, hydrogen, carbon dioxide, argon, nitrogen. Between the two phases, any reaction did not leak. The same applies to the interaction of the carrier gas with shared components. Depending on the consistency of the stationary phase, this method is divided into two categories. If the stationary phase is a solid support, then it is a gas-chromatography. But if the fixed phase - it is a liquid, which is on the inert carrier surface, there is meant gas-liquid chromatography. So, where do you use this method of investigation, and that is a gas chromatograph? In all this, we understand less. In what areas and what gas chromatographs are used? Gas chromatographic equipment was used for the analysis of complex mixtures by different separation of volatile substances. Chromatographic equipment differs quite complex device with several sensors, which allow an objective assessment of the qualitative and quantitative characteristics of the components of the sample. To perform the analysis of the substance is sufficient to introduce only a small sample into the chromatograph. In many models, the functionality allows you to simultaneously investigate multiple samples. The use of gas chromatographs true in the following sectors:  Production sphere of various kinds. For example, by chromatographic equipment successfully explore pharmaceuticals, food products, perfumes. Environmental analysis. Here, the subject analysis can be pesticides, poly-aromatic hydrocarbons, and many other complex substances. Oil and gas, mining. In these industries, the objective analysis of minerals and rocks is particularly important. Forensic medical examination and Criminalistics. For example, a study can be subjected to drugs or explosives. Laboratory analysis. In laboratories also frequently used chromatographic technique for the integrated assessment of different mixtures.     The combination of the gas chromatograph and the mass spectrometer allows for much better identification than if each device was used separately. It reduces the risk of error. Indeed, it is very unlikely that two different molecules behave in the same way both in a chromatograph and in a spectrometer. Thus, when a characteristic mass spectrum appears at a specific retention time in a GC / MS analysis, this increases the likelihood that the desired product is present in the sample.
