析結果が得られるという利点も伴う。The present invention was devised in view of the above-mentioned points, and a column for gas chromatography is filled with an organic material, and a heating furnace for heating this sample is provided with a gas chromatography column. By using a column oven, it becomes possible to easily analyze a trace amount of gas, which was difficult in the past. That is, the point that the improvement in FIG. 3 is added is in the 11 sample heating furnace. In the present invention, instead of this heating furnace, as a sample filling, by using a column for gas chromatography, by changing the length of the column, it becomes possible to freely change the sample amount,
This makes it easy to change the sample amount, which was difficult with conventional heating furnaces. Further, by using a precision oven for gas chromatography as a heating furnace, uniform and highly accurate heating becomes possible. Also, by configuring the above system,
Since the dead volume with respect to the gas flow path is extremely small, there is an advantage that extremely stable analysis results can be obtained even in the analysis of a small amount of generated gas.
