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.

chromatograms 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 TC scans under DUIS eluted by 5 mM oxalic acid solution as aqueous phase.
The
chromatograms of the reaction mixture using other substrates (5b-d) are shown in Figure 9.
HPLC
chromatogram 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.
