This experiment was the second blank run using the pyrolysis oven. The sample cup was not moved between the previous blank run, TID 25032, and this run, so there was no oppportunity for repeated exposure to the derivatization agent that contributed to the background in the previous experiment. There were no peaks identified in the evolved gas portion of this experiment, although the background rose slightly during the run on numerous m/z values, including those characteristic of toluene, hydrochloric acid, and sulfur dioxide.
