The Application of Laser Micropyrolysis Gas Chromatography-Mass Spectrometry System in Analyzing the Microscopic organic Matter

In this paper the composition and structure of the microscopic organic matter in coal (desmocollinite)are analyzed using the novel laser micropyrolysis gas chromatography-mass spectrometry system (LMPY-GC-MS). The LMPY-GC-MS system is character-ized by economical,fast-speed,accurate and no pretreatment and separation of samples,so it has a good future in science and technology.
