PURPOSE:To perform a separating analysis of all sizes of a molecule of a pyrolysis product, by a method wherein a sample collecting part is connected to a rear of a pyrolysis part where a gas chromatorgraph analysis is taking place, and is then linked to a liquid chromatograph analysis route. CONSTITUTION:A sample is introduced into a pyrolysis furnace 7 for pyrolysis. A small molecule product passes through a large molecule sample collecting tube 13 through a second switch cock K2 togetherwith carrier gas passing through a first switch cock K1, and reaches a gas chromatograph analysis route 6 after further passing through third and first switch cocks K3 and K1 for separation and analysis. Meanwhile, a large molecule one is adhered and collected to an inner wall of a sample collecting tube 13. The cocks K1 and K3 are then switched to supply carrier gas directly to the analysis route 6 through the cock K1 so that a small molecule sample can be continuously analyzed. Meanwhile, the collecting tube 13, togetherwith the pyrolysis furnace 7, forms a closed circuit to implant an organic solvent through a solvent implanting port 14, and the solvent is substituted for carrier gas. Then, through switching of the cock K2, the sample in the collecting tube 13 is supplied to a liquid chromatograph analysis route for separation and analysis. |
