一般描述

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.[1]

应用

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.[2] It may also be used to analyse hydrocarbons in expired air using GC equipped with FID.[3]
