Gas chromatography is one of the two most commonly employed types of procedures that is used in analysis of chemical compounds.

 

Gas Chromatography was the first type of chromatography that was available to be used commercially. The gas chromatograph was invented by A.J. Martin, who, along with another scientist, R.L.M. Synge, hinted at the possibility of the machine as early as 1941.

 The concept of gas chromatography was fairly well ignored for years after the publishing of the first paper that described how it would work. The process took many more years in the making due to the disbelief in the effectiveness of their projected new machine.

 

What gas chromatography does is to take the liquid mobile phase that is used in liquid chromatography, and to replace it with a gas that is suitable for finding the substance you are seeking. The reason for this is that there are higher concentrations of solutes in the gas as opposed to the liquid. For this reason, gas chromatography is more rapidly accomplished than liquid chromatography, although certainly not the short time span that you will see portrayed in the movies and on television.

 

The first use of a gas chromatograph was to isolate fatty acids. It was used with a micro burette in place as the detector. The introduction of this first instance of gas chromatography was an amazing success. Gas Chromatography and areas of GC analysis took off at an astounding rate, and evolved into a multi-million dollar business. The evolution took just about four years.

 

In addition to this, the process of this form of chromatography was among the first of the analytical type processes that was linked to a computer, which aided in controlling the analytical process, as well as helping to process the information and offer reports about the test results. Of course, many other areas including HPLC and ion chromatography have data systems and sophisticated items of hardware at their control centre - the world has certainly changed.
