    Research output: Contribution to journalArticlepeer-review


    Methods for detecting and discriminating volatile organic compounds emitted by statutory pathogens in potato tubers are reported. Analyses were performed utilising headspace solid phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS). Principal component analysis of the data highlights the difference in volatile profiles of infected tubers and their controls. An instrument was developed comprising an automated SPME sampler and 8-metal oxide sensor array and was demonstrated to be capable of identification of infected material. © 2006 Elsevier B.V.
