A laser pyrolysis gas chromatograph (LPGC) system has been developed which allowed for the direct analysis of solid samples. The LPGC system consists of a Q-switched Nd:YAG laser as a fragmentation source, a gas chromatograph, a sample chamber, and a data acquisition/processing system. The LPGC system was applied to the analysis of polystyrene samples (standards and products), and the results were compared with those obtained from the conventional pyrolysis GC with a tube-furnace pyrolyzer. The chromatograph of a polystyrene standard sample obtained from LPGC showed the characteristic component peaks of styrene monomer, styrene dimmer, and styrene trimer, and showed simpler patterns than those obtained from the conventional pyrolyzer. The analysis of polystyrene products by LPGC showed different chromatogram patterns depending on the area to be analyzed by a laser beam
