    Assessment of within-package and lot-to-lot variability associated with quartz collection pads in the determination of metals in aerosol

    WAGSTAFF W.; JOZA P.; PAICO-AVILEZ H.; ZHENG T.; DONISA C.; RODRIGUEZ-LAFUENTE A.
    Labstat International Inc., Kitchener, ON, Canada
    Determining aerosol metals routinely requires an assessment of differences between test sample aerosol results and collection blanks. When using pad collection principles, the background levels associated with metals from the quartz pad can make the...

    A statistical analysis of variability in polyaromatic hydrocarbons (PAHs) from reference and commercial cigarettes

    WAGSTAFF W.; RICKERT W.; JOZA P.
    Labstat international ULC, Kitchener, Ontario, Canada
    This study was conducted to characterize the variability of mainstream PAH emissions data and to investigate the ability to detect differences amongst products. The mainstream yields of a reference cigarette (Kentucky Reference 3R4F) were obtained...

    Analysis of hazardous and potentially hazardous tobacco smoke constituents: methodology and yields of benzo[b]furan, acetamide, acrylamide and nitrobenzene from commercially available tobacco products

    JOZA P.; BAO M.; WU J.; MASTERS A.; WAGSTAFF W.; RICKERT W.
    Labstat International ULC, Kitchener, ON, Canada N2C 1L3
    The recent FDA publication of a list of harmful and potentially harmful constituents has resulted in the development of a number of new or revised analytical methods for tobacco smoke chemistry. Analysis of the title compounds was achieved by...
