Though the process has seen various transformations in terms of technology used and the equipment utilized but the fundamentals still remain the same. A liquid or a gaseous sample is injected into a mobile phase also known as the carrier gas and it is then passed through a stationary phase. A column the main part of the process is done, a column which is a piece of metal or glass tubing holds the stationary phase which is constituted of a layer of thick liquid on the surface of solid particles.
The principle utilized here is that different chemicals exit atthe end of the column at different times, and at the end, the detection and identification of the chemicals are done electronically. Thus column selectionis the main thing that is to be taken into consideration while understanding your requirements from the gas chromatography. The functional groups present in the chemical and the polarity of the mixture is the deciding factor of the selection of the column.

PID Analyzers
When someone talks about detection techniques to be utilized mainly for organic compounds the first device which pops up in the mind is the PID Analyzers. They aresuited to detect the presence of the compound from a parts per million (PPM) concentration to parts per billion (PPB) concentrations. The best part is that they provide quick readings and have the ability to operate in a continuous manner. The major area of use as stated earlier is to detect volatile organic compounds which include fuels, plastics and their derivatives, lubricants solvents, and many more chemicals.
PID’s full form is photoionization detectors, in this process, the molecules are broken into positively charges ions by the high-energy photons which belong to the ultraviolet range. Resultantly the charges ions produce an electric current which is subsequently detected by a detector. The amount of current produced the directly proportional to the number of charged particles produce which is a reflection of the concertation of the product in the sample.
These analyzers are having high sensitivity and are best for compounds like Toluene, Benzene, Xylene, etc. The in-situ analysis is possible as no Tedlar bags and no lab analysis are possible due to this technology. For all your analytics requirements Quadrexcorp has brought to you the best of the best PID Analyzers. It is advisable to visit the website and have a detailed outlook of the devicesavailable and the configurations. The best deals are available for the quality products which will suit all your requirements.
