QCM sensor array for monitoring terpene emissions from odoriferous plants

摘要: An e-nose comprised of six sensing channels each coated with a molecularly imprinted polymer (MIP) selectively interacting alpha-pinene, thymol, estragol, linalool, and camphor, respectively, was designed. When applying it for continuous online surveillance terpenes emitted from basil peppermint leaves as criterion freshness, very appreciably reproduced the emanation patterns these plants shown by GC-MS. Chromatography yielded variety in concentration range below 70 ppm. Trend lines obtained were corroborated GC-MS also fit usual conduct observable human nose.
