From SAM Instrument Background to Martian Signal: Challenges of Solid Sample Analyses on Mars

Abstract : Taken togeth er, these results indicate that the internal SAM sources create a background that challenge s the analysis of solid samples in search for organics , cr eating interferences between terrestrial and possible indigenous carbon sources. We have be en exploring the possibility of SAM - derived C contributions to chlorohydrocarbon generation. Current observations pro vide no direct link between SAM internal sources and the chlorohydrocarbons detected on Mars, thus a martian organic contribution to the c hloromethanes, dichloroalkanes and chlorobenzene detected at CB is possible .
