Because the sample in the bottle is incubated for a sufficient time to reach the gas-liquid equilibrium, the appropriate volume of gas can be volatilized for the sample to be drawn into the chromatogram. Otherwise, the amount of gas volatilized from the sample at normal temperature is small and not stable enough. It is not possible to determine at all.
