| Abstract: | This paper introduces results of research on transformation mechanism,temperature and time of organic carbon during analysis of rock and mineral samples by gas chromatography,as well as conditions for eliminating carbonate constituent that may produce carbon dioxide gas.The research has solved the problem of connecting the chemical processing and instrument determination.The newly established method is characterized by high sensitivity,good exactitude,simple and fast operation,and may be applied to the determination of organic carbon in rock,mineral,as well as sediment samples. |
