    On-line puff resolved analysis of cigarette smoke for product profiling using soft-photoionisation mass spectrometry

    EHLERT S.(1,2); HEIDE J.(2); BENTE v FROWEIN M.(1); WALTE A.(1); ZIMMERMANN R.(2)
    (1) Photonion GmbH, Schwerin, Germany; (2) University of Rostock, Dept. of Analytical Chemistry, Rostock, Germany
    Photo ionisation-time of flight mass spectrometry (PI-TOFMS) has been established for the on-line analysis of complex gas mixtures. Therefore, it is a suitable tool for puff resolved chemical fingerprint screening of cigarette smoke. This capability can ...

    On-line puff resolved analysis of cigarette smoke, e-cigarette vapour and vapour of tobacco heating products

    EHLERT S.(1,2); HEIDE J.(1); WALTE A.(2); ZIMMERMANN R.(1)
    (1) University of Rostock, Dept. of Analytical Chemistry, Rostock, Germany; (2) Photonion GmbH, Schwerin, Germany
    Photo ionisation-time of flight mass spectrometry (PI-TOFMS) has been established for on-line analysis of complex gas mixtures. Cigarette smoke, e-cigarette vapour and the vapour of tobacco heating products provide good examples for such complex gas ...

    Evaluation of NCDA&CS boron sufficiency ranges for flue-cured tobacco

    JERNIGAN C.H.(1); HARDY D.H.(1); HICKS K.A.(1); McGINNIS M.S.(1); FISHER L.R.(2); VANN M.C.(2)
    (1) North Carolina Department of Agriculture and Consumer Services, Raleigh NC USA; (2) North Carolina State University, Raleigh NC USA
    Boron (B) is an essential micronutrient for optimum plant growth of flue-cured tobacco and is required in trace amounts (<1.0 lb B/acre). Since use of premium tobacco fertilizer grades that contain trace amounts of B are not typical in today’s ...
