    Paper filters – the influence of different paper compositions and paper properties on filtration efficiency and pressure drop

    BACHMANN S.; GLEINSER M.; VOLGGER D.
    delfortgroup AG, Traun, Austria
    Smoke yields, smoke composition and the taste of a cigarette can be modified by changing different parts of the cigarette, especially the different filter design. Cellulose acetate is currently the most common material for cigarette filters, but also ...

    Using residual length data to estimate the rate of self-extinguishment of banded cigarettes

    EITZINGER B.(1); RIVAS CANO A.(2)
    (1) delfortgroup AG, Traun, Austria; (2) JT International Germany GmbH, Trier, Germany
    For non-banded lower ignition propensity (LIP) cigarettes the residual length of extinguished cigarettes has been shown to be useful to more precisely estimate the rate of self-extinguishment compared to just counting self-extinguished cigarettes (ISO ...

    The pore size distribution of naturally porous cigarette papers and its relation to air permeability and diffusion capacity – Part 1

    GLEINSER M.(1); EITZINGER B.(2); BACHMANN S.(1); VOLGGER D.(1)
    (1) Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria; (2) delfortgroup AG, Traun, Austria
    In the tobacco industry it is well known that porosity is one of the most significant physical properties of cigarette paper. There are indirect as well as direct methods to characterise this parameter. Measurement of the diffusion capacity and the air ...

    The pore size distribution of naturally porous cigarette papers and its relation to air permeability and diffusion capacity – Part 2

    EITZINGER B.(1); GLEINSER M.(2); BACHMANN S.(2); VOLGGER D.(2)
    (1) delfortgroup AG, Traun, Austria; (2) Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria
    Several publications have shown in the past, on theoretical grounds and by actual measurements, that the perforation of cigarette papers causes a substantial increase in air permeability, while the diffusion capacity increases comparably less. These ...

    Comparison of the variability in smoke yield data when smoking cigarette brands onto a 44mm cambridge filter pad with a rotary smoking machine.

    MAYR M.; CASE P.
    delfortgroup/Wattenspapier, Wattens, Austria
    The objective of this study was to evaluate the variation in tar, nicotine and CO when smoking low-yield cigarette brands using a common and a modified Cambridge filter pad holder. Several low yield cigarettes as well as cigarettes with target yields up ...

    Comparison of two maximum-likelihood estimators of the rate of self-extinguishment in the ISO 12863 test

    EITZINGER B.(1); COBURN S.(2); CASE P.(3)
    (1) delfortgroup AG, Traun, Austria; (2) British American Tobacco, Group R&D, Southampton, UK; (3) Consultant to delfortgroup AG, Traun, Austria
    To check the compliance of cigarettes with low ignition propensity regulations, it is necessary to estimate the rate of self-extinguishment a cigarette will have, when tested according to ISO 12863. One way to do this is to actually perform the test ...
