Application
Sample loops may be used in GC system consisting headspace samplers for the gas analysis to determine the impact of biochar on CO2 and N2O production. It may also be used to analyse hydrocarbons in expired air using GC equipped with FID.
General description
In loop systems, sample vials are pressurized after equilibrium by carrier gas. Nevertheless, the vial opens temporarily towards the sample loop of a gas sampling valve and not to the column. The pressurized headspace gas from vial fills up the sample loop from which it is injected to the GC.
