Abstract
Discrepancies in the determination of anthracene in dihydroanthracene were revealed when mass spectrometric analyses were compared with ultraviolet spectrophotometric data. A limited investigation indicated that dehydrogenation of the hydroaromatic in the mass spectrometer inlet system can be minimized but not eliminated. A combination of both ultraviolet and mass spectrometric analyses will be necessary to determine the components present in samples containing hydroaromatic structures.
