Luna 16 and Luna 20 samples were analyzed for volatilizable species using vacuum pyrolysis to 1400°C. The major gaseous products evolved (ranging from 10-650 g/g) were H 2 O, CO, CO 2 , N 2 and CH 4 . Minor components (all < 10 g/g) included NH 3 , HCN, NO, SO 2 , H 2 S, C 2 H 2 , C 2 H 4 , C 2 H 6 , C 3 H 6 and higher hydrocarbons, benzene, toluene, and the polymeric contaminants Teflon ® and silicone oil. The total carbon and nitrogen contents ( g/g) for these sieved samples (< 125 m) were: Luna 16--C 418, N 134 and Luna 20--C 380, N 80.
