To use a gasy substance of improved safety as an internal standard substance for improving analysis reliability, and at the same time easily and automatically adding the internal standard substance by adding the gasy internal standard substance to a component to be inspected before being introduced to an analysis part.
By breathing a purge gas into a liquid sample by bubbling, a component to be inspected in the sample is forced out to a vapor phase. When an internal standard gas is added (addition position A) through a purge gas supply line 17 at the upstream side of a purge container 11, the internal standard substance passes through the purge container along with a purge gas. More specifically, a purge gas is sent from the purge gas supply line 17 into a liquid sample 16 held in the sample container 11 for bubbling, the component to be analyzed in the sample 16 is forced out to the vapor phase of the container 11, and the purge gas containing the component to be inspected is sent out into a concentration pipe 14 via an analysis part introduction line 18, and is adsorbed to be concentrated by the concentration pipe 14 to be analyzed at an analysis part 2.
