    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 ...

    Tunable diode laser infrared spectroscopy for the simultaneous monitoring of cigarette smoke and filter ventilation

    PARRISH M.E.; HARWARD C.N.; VILCINS G.
    Philip Morris USA, Richmond, VA, USA
    A computer-controlled high resolution infrared tunable diode laser (TDL) system has been developed to determine simultaneously the concentration of a smoke component and the filter ventilation of a cigarette during smoking. The approach selected was to ...

    Pattern recognition of cigarette smoke analyzed by capillary gas chromatography

    GOOD B.W.; HSU F.S.; PARRISH M.E.
    Philip Morris USA, Research Center, Richmond, VA, USA
    Initially, differentiation between two cigarette types was accomplished by comparing the organic gas phase profiles obtained using glass capillary gas chromatography. Although the use of a computer was instrumental in achieving these comparison profiles, ...
