where [S.sub.f] is the sulfur content of the shale oil, and [A.sub.p] and [A.sub.f] are the total peak areas of the GC-SCD chromatograms
of the product and shale oil, respectively.
The not referenced peaks on the Figure 3 chromatogram
correspond from left to right to heptane (solvent), methyl octanoate and 4-methyl-phenol, respectively.
The class of n-alkanes was also identified by extracting chromatograms
for the m/z 57.06983 (exact mass: 57.06988, error: -0.87 ppm).
In particular, an Enbrel chromatogram
revealed a higher relative abundance of late eluting species.

obtained from LC-LTQ MS analysis of microsomal incubations containing LIM, GSH, NAL, and NADPH in the absence microsomes (a) or in presence of HLMs (b) or MLMs (c).
Figure (5) shows the chromatograms

of local sample is presented in Figure 4.
Each experiment was therefore described by the area of the 143 peaks recorded in the chromatogram
. Figure 1 reports the results obtained: the peaks are reported on x-axis in order of elution, while the corresponding areas are reported on the y-axis (the darker the marker, the highest the sample amount).

The identification of the components of the products was confirmed using total ion chromatograms
and fragmentation pattern.
