    A reliable method for the routine analysis of trace carbonyl compounds, including formaldehyde, acetaldehyde, acetone, propionaldehyde, acrolein, methyl-ethyl ketone (MEK), butyraldehyde, and crotonaldehyde, in tobacco products is presented. One gram of ...
  2. TSRC, Tob. Sci. Res. Conf., 2013, 67, abstr. 54

    Profiling of various tobacco products using headspace - solid phase microextraction - gas chromatography mass spectrometry (HS-SPME-GCMS).

    Labstat International ULC, Kitchener, ON, Canada
    The aim of this research was to develop a rapid screening method that could be applied to the detection of flavors currently found in tobacco products. HS-SPME-GCMS was the chosen technique since this approach has been used previously in the qualitative ...
  3. TSRC, Tob. Sci. Res. Conf., 2013, 67, abstr. 73

    An improved high performance ion chromatography suppressed conductivity detection method for the determination of ammonia in tobacco and tobacco smoke samples.

    Labstat International ULC, Kitchener, ON, Canada
    An improved HPIC method has been developed and validated for ammonium analysis using a high efficiency analytical column (smaller particle size, 5.5 um and narrower inner diameter, 3 mm). Compared to the widely used Health Canada HPIC method, the improved ...
