Preservation of Organic Molecules in Mars-Analog Samples Using Pyrolysis and Derivatization GCMS Experiments from the SAM Instrument
2018
This
ongoing
work
will help
us
iden-
tify the MTBSTFA by
-
products present in the SAM
chromatograms and the
high molecular derivatives de-
tected in the
last
OG run
.
The
investigation
will also
en-
able a better minerals
target
selection
for the preserva-
tion of organic molecules on Mars and help
the identifi-
cation of
the
precursors of the
organics
detected
on
Mars
.
These experiments
will
also
be
helpful to
better
understand the limits and biases of the flight
