    Chemical studies of the semi-volatile weakly acidic fraction from cigarette smoke condensate

    ARNARP J.; PETTERSON T.; JUNKER N.; ENZELL C.
    Swedish Tobacco Company, Research Dept., Stockholm, Sweden
    Smoke condensate from regular blend-type cigarettes has been separated into volatile, semi-volatile and non-volatile fractions by distillation under reduced pressure at low temperature using CO2 as carrier gas. The semi-volatile fraction was subsequently ...

    Swedish Tobacco Company, Research Dept., Stockholm, Sweden
    The biological activity of the semi-volatile part of cigarette smoke particulate matter has been examined, since the constituents of this material can be removed by selective filtration. Cigarette smoke condensate, obtained from regular blend-type ...
