Terpene detection and quantitation from chromatogram profiles were acquired using selected ion monitoring (SIM) mode during full scan analysis and mass spectra were obtained with a quadrupole\u2010type mass spectrometer.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The new trapping method produced reliable qualitative profiles of oilseed rape VOCs. Typical emissions of monoterpenes (myrcene, limonene) and sesquiterpenes (\u03b2\u2010elemene, (E,E)\u2010\u03b1\u2010farnesene) were found for the different concentrations tested. One\u2010way analysis of variance for quantitative results of (E,E)\u2010\u03b1\u2010farnesene emission rates showed a Cd concentration effect.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n This inexpensive glass chamber has potential for wide application in laboratory sterile approach and replicated research. Moreover, the non\u2010invasive dynamic sampling technique could also be used to analyse volatiles under both abiotic and biotic stresses.<\/jats:p>\n
