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.

TL;DR: In this paper, the authors build an exhaustive molecular database to support the interpretation of SAM results by identifying all the chemical species produced from Tenax® adsorbents, by determining the thermal degradation by-products of Tenax®, (2) the effect of tenax® conditioning on the formation of 10ax® byproducts, (3) the impact of MTBSTFA or a mixture of MTbSTFA and DMF on Tenax´ decomposition, and (4) the reaction between Tenax''s and calcium perchlorate.

TL;DR: Thermochemolysis of seven nucleobases-adenine, thymine, uracil, cytosine, guanine, xanthine, and hypoxanthine-in tetramethylammonium hydroxide (TMAH) was studied individually by pyrolysis gas chromatography mass spectrometry in the frame of the Mars surface exploration to constrain the analytical capabilities of the thermochemicalolysis experiments that will be performed on Mars.

TL;DR: Results demonstrate that flash pyrolysis yields more diversity and greater abundances of TMAH thermochemolysis products than does the SAM-like ramp pyrolynsis method, and the presence of calcium perchlorate does not significantly impact the recovery rate of fatty acids with TMAh thermochemistryolysis under laboratory conditions, which is promising for the detection of fatty fatty acids via T MAH thermochemicalolysis with the SAM and MOMA instruments on Mars.

TL;DR: Health data from the gas chromatography (GC) module onboard the SAM instrument was presented to assess the analytical performances evolution of a GC device in the Martian environment through 3 years as mentioned in this paper, and the results showed that the GC module performed well in the Mars environment.
