3 method summary
In the closed vessel and at a certain temperature, the volatile components in the sample are present between the gas phase (headspace) and the matrix (liquid or solid)
With balance. When the equilibrium is reached, the gas phase is introduced into the gas chromatographic separation, and after the matrix correction, the volatile components can be determined.
The content of the sample.
4 reagents and materials
4.1 organic solvents
The following solvents should be chromatographed pure. benzene (C6H6), toluene (C7H8), ethylbenzene (C8H10) and xylene (C8H10).
4.2 matrix correction agent
Glycerol triacetate (C9H14O6). pure chromatographic.
4.3 gas
4.3.1 Hydrogen. Before use, use dehydration device, silica gel, molecular sieve or activated carbon for purification.
