    Compensation for ambient conditions effects on Multi-capillary Pressure Drop Standards Calibration

    COLARD S.; TRINKIES W.; CHOLET G.; CAMM B.; AUSTIN M.; GUALANDRIS R.
    Altadis - Imperial Tobacco Group, Research Center, Fleury les Aubrais, France
    The draw resistance of cigarettes and the pressure drop of filters are both major physical parameters for the Tobacco Industry. So, these parameters must be measured with reliability. For these measurements, one uses specific equipment calibrated...

    Influence of cigarette paper, porosity and amount of citrate, and of filter ventilation on the Hoffmann analytes

    LOUREAU J.M.; BIESSE J.P.; CLARISSE G.; VIDAL B.; DEBERLY S.; LE MOIGNE C.; LE BOURVELLEC G.
    Papeteries de Mauduit, Quimperlé, France
    The measurement of Hoffmann analytes, since it has been requested in Canada and then in some of the US states and in Brazil, has become necessary. If a number of studies have already been published on the influence of some cigarette design tools...
