Release of organic compounds from some Antarctic CI and CM chondrites by laboratory heating
Thermal release of organic compounds from three CI chondrites (Belgica (B)-7904,Yamato (Y)-82162,and Y-86720) and three CM chondrites (Y-74662,Y-791198,and Y-793321) was examined by DTA/TG-MS analysis. For identification of the compounds released, Y-791198 was also examined by DTA/TG-GC/MS analysis....
