Phenolics in selected European hardwood species by liquid chromatography-electrospray ionisation mass spectrometry.
The phenols in beech (Fagus sylvatica), birch (Betula pendula) and ash (Fraxinus excelsior) wood dusts were compared using a mass spectrometer fitted with an electrospray ionisation interface with liquid chromatographic separation. Hardwood dust is a carcinogen, and an analysis of the polyphenol profile is a useful method for identifying the dust source in workplace air. The mass spectrometer was operated in both the negative and positive ion modes. Phenolic compounds were identified by comparing mass spectra and retention times from liquid chromatography with those for standard compounds and data in the literature. The phenol contents of the studied wood species varied considerably, and only a few common compounds were found in them.[1]References
