This experiment was a drilled solid sample experiment, designated QL1.
This run (TID 25412) was part 1 of a two-part series for the QL1
experiment, consisting of the evolved gas analysis (EGA) and gas
chromatograph (GC) analyses. Part 2, (TID 25413) consisted of
analysis with the tunable laser spectrometer (TLS). This run
revealed the continued presence of products of the derivatization
reagent, N-methyl-N-tert-butyldimethylsilyl-trifluoroacetamide
(MTBSTFA), adsorbed onto the sample. For estimation of abundances of
volatile compounds detected in EGA, the background was subtracted as
a constant value, either at the start or end of the run or before
major peaks. An exception to this was CO2, which was modeled with a
downward-trending background throughout the run. Uncertainties in
abundances, deriving from statistical noise, background subtraction,
calibration factors, assumptions regarding ionization cross-sections
for the relevant compounds, and isobaric interferences, are estimated
at 10-20% of the values.
