Journal ArticleDOI
Potential precursor compounds for chlorohydrocarbons detected in Gale Crater, Mars, by the SAM instrument suite on the Curiosity Rover
Kristen E. Miller,Jennifer L. Eigenbrode,Caroline Freissinet,Daniel P. Glavin,Benjamin Kotrc,Pascaline Francois,Roger E. Summons +6 more
TL;DR: In this article, analog experiments were conducted under conditions similar to SAM gas chromatography-mass spectrometry analyses, in which they pyrolyzed potential precursor compounds in the presence of various Cl salts and Fe oxides that have been identified in Martian sediments.
Journal ArticleDOI
Development of a gas chromatography compatible Sample Processing System (SPS) for the in-situ analysis of refractory organic matter in martian soil: preliminary results
Arnaud Buch,Robert Sternberg,Cyril Szopa,Caroline Freissinet,Caroline Freissinet,C. Garnier,C. Garnier,J. El Bekri,C. Rodier,Rafael Navarro-González,François Raulin,Michel Cabane,Moncef Stambouli,Daniel P. Glavin,Paul R. Mahaffy +14 more
TL;DR: In this article, a new sample preparation system (SPS) compatible with gas chromatography-mass spectrometry (GC-MS) has been developed for the in situ analysis of complex organic molecules in the Martian soil.
Journal ArticleDOI
Magnesium sulfate as a key mineral for the detection of organic molecules on Mars using pyrolysis
Pascaline Francois,Cyril Szopa,Arnaud Buch,Patrice Coll,Amy McAdam,Paul R. Mahaffy,Caroline Freissinet,Daniel P. Glavin,Rafael Navarro-González,Michel Cabane +9 more
TL;DR: In this paper, the pyrolysis of organic molecules trapped in magnesium sulfate, in the presence or absence of calcium perchlorate, was studied, and it was shown that trapped organics can undergo some oxidation and sulfuration during the process.
Journal ArticleDOI
In Situ Analysis of Martian Regolith with the SAM Experiment During the First Mars Year of the MSL Mission: Identification of Organic Molecules by Gas Chromatography from Laboratory Measurements
Maeva Millan,Cyril Szopa,Cyril Szopa,Arnaud Buch,Patrice Coll,Daniel P. Glavin,Caroline Freissinet,Caroline Freissinet,Rafael Navarro-González,Pascaline Francois,D. Coscia,Jean-Yves Bonnet,Samuel Teinturier,Michel Cabane,Paul R. Mahaffy +14 more
TL;DR: In this paper, the analytical capabilities of the MXT-CLP GC column (SAM GC-5 channel) were evaluated for nearly all of the GC-MS analyses of the martian soil samples carried out with SAM to date.
Journal ArticleDOI
Identification of Chlorobenzene in the Viking Gas Chromatograph-Mass Spectrometer Data Sets: Reanalysis of Viking Mission Data Consistent With Aromatic Organic Compounds on Mars
Melissa Guzman,Christopher P. McKay,Richard C. Quinn,Cyril Szopa,Cyril Szopa,Alfonso F. Davila,Rafael Navarro-González,Caroline Freissinet +7 more
TL;DR: In this article, the authors reexamined the original, microfilm preserved, Viking gas chromatograph mass spectrometer (GCMS) data sets and found evidence for the presence of chlorobenzene in VL•2 data at levels corresponding to 0.08•1.0 ppb (relative to sample mass), in runs when the sample was heated to 350°C and 500°C.
