    (1) SQM S.A., Las Condes, Santiago, Chile; (2) Consultant Agronomic Engineer
    Tobacco growing areas in Chile are limited, however crop yield potential is high. Soil, climate, low presence of diseases and irrigation are factors responsible for high yields. Nitrogen is the main yield driver, mainly when the economic yield is a ...

    Puff-by-puff determination of gas phase acetaldehyde, HCN, NO and CO using FTIR spectrometry

    KOLLER K.B.; THOMAS C.E.; PARRISH M.E.; LEYDEN D.E.
    Philip Morris USA, Research Center, Richmond, VA, USA
    A multi-component, quantitative FTIR spectrometric method has been developed for the simultaneous determination of the concentrations of acetaldehyde, HCN, NO, and CO present in gas phase cigarette smoke. A 50 cc portion of gas phase cigarette smoke from ...

    Influence of smoke dilution and environmental conditions on the measured levels of ETS components

    PIADE J.J.; BLAKE C.; GERBER C.
    Philip Morris Europe, R&D, Neuchatel, Switzerland.
    Cigarette emission yields have often been used to compute ETS exposures in indoor environments, but this approach rests on many assumptions and experimental results in this domain vary widely. In order to gain more insight into this field, the following ...
