TL;DR: Tetramethylammonium hydroxide (TMAH) is one of the most popular methylation reagents that have been increasingly used for the detection of organic compounds within a wide range of samples, such as soil, coal, lacquer, lignin, polymers and for in situ analysis of solid samples by space experiments as mentioned in this paper.

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: In this article, the effect of the presence of calcium perchlorate on the pyrolysis products of N-tert-butyldimethylsilyl-N-methyltrifluoroacetamide (MTBSTFA) and N,N-dimethylformamide (DMF) was investigated.
