With this video you will have the chance to evaluate HOW
a gas chromatograph works and its components.
Howewer before that I want to give some brief information on Gaschromatography also known as GC, which is
one of the most powerful analytical techniques in organic chemistry .
Gas chromatography widespread in the sixties and still today is one of the main techniques
used in separation of complex mixtures.
Today with the term Gaschromatography we mean
the High Resolution Gas Chromatography or HRGC (high resolution gaschromatography),
which utilizes a capillary column, tecnology introduced
at the beginning of the eighties and that is practically today the only one used.
It is a rather widespread technique of analytical chemistry, based on partition
of components of a mixture to be analyzed between a liquid or solid stationary phase
and a gaseous mobile phase.
The distribution of different substances between the stationary phase and the mobile phase takes place
as a function of the affinity of each compound with the stationary phase, like in all chromatographs.
In this regard we have already talked about “in pills” of chromatography inside of the
“MANUSCRIPT”.
In the full version of the video you will have the opportunity to study “The GC”, which consists
of a series of components that each perform one own function.
Let’s see them specifically:
- Gaseous mobile phase
- Autosampler / injector
- Analytical column and column thermostat furnace
- Detector
- PC to elaborate data
