The major flavouring property of peppermint oil derives from its main constituent...
Bull. Spec. CORESTA Congress, Lisbon, 2000, p. 150, ST6 Measurements of particle numbers and diameters of sidestream cigarette smoke by laser-photodetection in an experimental room INTORP M.; JENNING W.R.; KANNENGIEßER D. H.F. & Ph.F. Reemtsma GmbH, Research & Development, Hamburg, Germany. The contribution of respirable suspended particles (RSP) from sidestream cigarette smoke (SS) to indoor air quality had been and is still an important factor to evaluate the contamination caused by smouldering cigarettes. To evaluate the contribution...
Bull. Spec. CORESTA Congress, Lisbon, 2000, p. 164, ST19 Strategies to assess the biological properties of tobacco smoke RÖPER W.; WIECZOREK R. H.F. & Ph.F. Reemtsma GmbH, Research & Development, Hamburg, Germany. In addition to measuring tobacco smoke analytes, there will be an increasing demand in the future to establish guidelines for testing the biological activity of tobacco smoke. Thus, testing methods have been identified which can provide valid data in...
