Abstract

International audience; Boththe Sample Analysis at Mars (SAM) and Mars Organic Molecule Analyzer (MOMA)instrumentsare able to identify organic material at the Martian surface and subsurface. Both experiments are equipped with pyrolysis-Gas Chromatography-Mass Spectrometry (Pyr-GC-MS)and derivatization reagents (MTBSTFA)that will allowthe analyzerefractory com-pounds,making them more volatile and protecting the labile chemical groups. In order to improve the Pyr-GC-MS analysis, TMAH (tetramethylammonium hydrox-ide) will be used on MOMA and SAM to extract refrac-tory compounds (macromolecules, kerogen, etc.) and protect polar compounds released from the pyrolysis ex-periment.We performed pyrolysis and TMAH-thermochemolysis of a Martian regolith simulant (JSC-Mars-1) to optimizeanalytical parameters, especially the thermochemolysis temperature, to ensure the success of the near future in situthermochemolysis analyses on Mars.

Abstract

International audience; Introduction: The Sample Analysis at Mars (SAM) instrument suite is currently operating in the Curiosity rover in Gale Crater, Mars. SAM carries nine sealed wet chemistry cups, seven which contain a mixture of N-methyl-N-(tert-butyldimethylsilyl) trifluoroacetamide and dimethylformamide (MTBSTFA:DMF 4:1) for derivatization and two that are filled with tetramethylammonium hydroxide (TMAH) and methanol for thermochemolysis [1]. Here we describe the first derivatization experiment performed on Mars with SAM that includes the puncture of one of the MTBSTFA cup. Overview of wet chemistry. One of the primary goals of the SAM investigation is the search for organic compounds on Mars. The wet chemistry cups onboard SAM are intended to make complex organic molecules more volatile derivatized products that can be readily analyzed by GCMS. An example of the MTBSTFA derivatization reaction with an amino acid is shown in Figure 1. The seven derivatization cups contain 0.5 mL of a mixture of MTBSTFA and DMF in a 4:1 ratio. These cups also contain trace standards (36.2 nmol of 3-fluorovaline and 24.2 nmol of pyrene) (Figure 1) for calibration and verification purposes.

Abstract

International audience; These experiments represent the first successful MTBSTFA derivatization experiment on Mars. Several MTBSTFA reaction products were generated during reactions with the Cumberland mudstone sample at elevated temperatures, with some products containing mass fragments up to m/z 358. We are continuing anthe alysis of this interesting data set to identify these derivatization products that should shed additional light on the chemical nature of the organic matter present in the Cumberland mudstone.

Abstract

International audience; The Sample Analysis at Mars (SAM) instrument on the Curiosity rover is designed to determine the inventory of organic and inorganic volatiles thermally evolved from solid samples using a combination of evolved gas analysis (EGA), gas chromatography mass spectrometry (GCMS), and tunable laser spectroscopy [1]. The first sample analyzed by SAM at the Rocknest (RN) aeolian deposit revealed chlorohydrocarbons derived primarily from reactions between a martian oxychlorine phase (e.g. perchlorate) and terrestrial carbon from N-methyl-N-(tert-butyl-dimethylsilyl)trifluoroacetamide (MTBSTFA) vapor present in the SAM instrument background [2]. No conclusive evidence for martian chlorohydrocarbons in the RN sand was found [2]. After RN, Curiosity trav-eled to Yellowknife Bay and drilled two holes separated by 2.75 m designated John Klein (JK) and Cumber-land (CB). Analyses of JK and CB by both SAM and the CheMin x-ray diffraction instrument revealed a mudstone (called Sheepbed) consisting of ~20 wt% smectite clays [3], which on Earth are known to aid the concentration and preservation of organic matter. Last year at LPSC we reported elevated abundances of chlorobenzene (CBZ) and a more diverse suite of chlorinated hydrocarbons including dichloroalkanes in CB compared to RN, suggesting that martian or mete-oritic organic compounds may be preserved in the mudstone [4]. Here we present SAM data from additional analyses of the CB sample and of Confidence Hills (CH), another drill sample collected at the base of Mt. Sharp. This new SAM data along with supporting laboratory analog experiments indicate that most of the chlorobenzene detected in CB is derived from martian organic matter preserved in the mudstone [5].
