Sporinite peaks from

The Py-MS experiments have provided detailed information on the labile organic structures found in the maceral concentrates. The utility of being able to obtain precise mass measurements is demonstrated in Table II where a small selection of peaks from the pyrolysis of the Brazil Block seam sporinite is listed. Note that at nominal m/z = 108 and 122 there are actually three distinct peaks corresponding to a quinone, an alkyl-phenol and a hydrocarbon. Normally with nominal mass pyrolysis data these peaks would only be assigned to alkyl phenols. All three peaks... 

Figure 1. This bar graph shows the variation in the m/z = 108 peak components from Py-MS for a series of macerals. The sporinite and vitrinite are separated from the Brazil Block seam coal.
