Conf., 2011, 65, abstr. 07 Analysis of multiple classes of cigarette smoke constituents by comprehensive two-dimensional gas chromatography with time of flight mass spectrometry (GCxGC-TOFMS). HUMSTON-FULMER E.; BINKLEY J.; RILEY M. LECO Corporation, Saint Joseph, MI, USA The Food and Drug Administration now has the authority to regulate cigarettes, cigarette tobacco, and smokeless tobacco products. Among the areas of regulation is the monitoring of tobacco smoke constituents. It is well known that tobacco smoke is a...
TSRC, Tob. Sci. Res. Conf., 2010, 64, abstr. 12 Quantitation of pesticides in flue-cured tobacco by comprehensive two-dimensional gas chromatography-time of flight mass spectrometry (GCXGC-TOFMS) BINKLEY J.; PUGH S. LECO Corporation, Saint Joseph, MI, USA Flue-curing is a tobacco curing process used to produce cigarette tobacco. The process typically takes approximately a week and generates a tobacco that is high in sugar with a medium to high nicotine content. Tobacco is known to contain thousands of...
TSRC, Tob. Sci. Res. Conf., 2009, 63, abstr. 08 Analysis of pesticides in smokeless tobacco extracts by comprehensive multi-dimensional gas chromatography-time of flight mass spectroscopy (GCxGC-TOFMS) BINKLEY J.; PUGH S. LECO Corporation, Saint Joseph, MI, USA Smokeless tobacco is known to contain several thousand analytes making it an extremely difficult matrix in which to identify pesticide residues. Current methodologies incorporate the use of complex, time consuming sample cleanup techniques to...
