Description
It is designed to separate mixtures of gases or volatile liquids and identify components of the mixtures by their specific retention times.
The GC operates at room temperature, eliminating long warming up periods.

All specifications can be found in the product manual, see downloads.
The Gas Chromatograph can be used for analysing different gasses, such as:
- Lighter gas: Gas from a cigarette lighter contains propane, methylpropane and butane. Small amounts of ethane and pentane are also often detected. Various brands contain different compositions. By comparing the chromatograms of two different lighters, the qualitative as well as the quantitative aspects of gas chromatography can be discussed.
- Biogas: Gas from a ditch or from a (self-made) biogas installation can be investigated.
- Methanol in white wine: White wine often contains small amounts of poisonous methanol. With a polar column methanol can be detected. First the wine should be distilled. To prevent non-volatile components to reach the column the distillate should be injected.
- Natural gas: The first peak in the chromatogram obtained from natural gas is from
- Other components such as propane and butane can also be detected. Natural gas contains about 14% nitrogen. The detection sensor is not sensitive to nitrogen gas.
