  1. CORESTA Meeting, Smoke Science/Product Technology, 2019, Hamburg, STPOST 18 (also presented at TSRC 2019)

    Comparison of a flame ionization detector (GC/FID) to a nitrogen-phosphorus detector (GC/NPD) for gas chromatographic determination of nicotine in conventional and ultra-low nicotine tobacco blends

    STINSON A.; STEELMAN D.; CLARK T.J.
    Liggett Group LLC, 100 Maple Lane Mebane NC, U.S.A.
    The established CORESTA method to determine nicotine in tobacco uses a gas chromatograph coupled with a flame ionization detector (GC/FID) (CRM 62) that uses mass spectrometry (GC/MS) (CRM 87). These methods were developed to evaluate conventional tobacco ...

    CTP submissions – tips and insight for preparing an electronic submission

    SMITH J.K.(1); SHOLTES D.(1); GLATSTEIN S.(1); ANGERMEIER G.(2)
    (1) US Food and Drug Administration (FDA), Silver Spring, MD, USA; (2) WiseDesign, McLean, VA, USA
    Currently, tobacco product submissions are organized differently across application types and often, across applicants, and are received in a format that is not amenable for reviewers to organize and easily find what they need. This “unstructured” format ...

    Comparison of the acetaldehyde, formaldehyde, and acrolein yields in cigars under different smoking regimens using a linear cigarette smoking machine

    YOUNG M.; CECIL T.L.; JOHNSON T.; FENG S.
    US Food and Drug Administration (FDA), Calverton, MD, USA
    Currently, there is very little information on the mainstream smoke yields of carbonyl compounds (e.g., formaldehyde, acetaldehyde, and acrolein) in cigar tobacco products. This study used a standard linear smoking machine and puffing protocols to provide ...
