一般描述

This 303 stainless steel sample loop does not include zero volume nuts (22989 and 22991).

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.

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