TSRC, Tob. Sci. Res. Conf., 2018, 72, abstr. 109 An improved method for the determination of sodium propionate in tobacco products WILLIAMSON F.; BAILEY J. Global Laboratory Services, Wilson, NC, USA Sodium propionate is a preservative with fungicidal properties that is often added to tobacco, primarily smokeless tobacco products, to prolong shelf life. Several regulatory agencies, including Health Canada and ANVISA, require the testing of sodium...
CORESTA Congress, Quebec, 2014, Smoke Science/Product Technology Groups, ST 73 A new method for the analysis of carbonyl compounds in e-cigarette liquids WILLIAMSON F.; MARTIN A. Arista Laboratories, Richmond, VA, U.S.A. Carbonyl compounds (carbonyls) are organic molecules that contain a carbon atom double-bonded to an oxygen atom. Specifically these include compounds known as aldehydes and ketones that are usually found in traditional mainstream tobacco smoke and...
CORESTA Congress, Quebec, 2014, Smoke Science/Product Technology Groups, ST 75 Selected primary aromatic amines (PAAs) in e-cigarette vapor by GC-MS MARTIN A.; WILLIAMSON F. Arista Laboratories, Richmond, VA, U.S.A. Primary aromatic amines (PAAs) are compounds of interest to a number of tobacco regulators and are routinely found in mainstream (MS) tobacco smoke. Six of the 93 compounds currently included on the United States Food and Drug Administration (FDA)...
TSRC, Tob. Sci. Res. Conf., 2014, 68, abstr. 14 Selected primary aromatic amines (PAAs) in e-cigarette vapor by GC-MS MARTIN A.; WILLIAMSON F. Arista Laboratories, Richmond, Virginia, USA Primary aromatic amines (PAAs) are compounds of interest to a number of tobacco regulators and are routinely found in mainstream (MS) tobacco smoke. Six of the 93 compounds currently included on the US FDA's established list of harmful and...

TSRC, Tob. Sci. Res. Conf., 2013, 67, abstr. 07 Benzo[a]pyrene in tobacco products by ultra-pressure liquid chromatography with fluorescence detection using its deuterated analog as an internal standard. SODEN C.; WILLIAMSON F. Arista Laboratories, Inc., Richmond, VA, USA Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon (PAH) classified by the International Agency for Research on Cancer (IARC) as a group 1 carcinogen. BaP is formed as a product of incomplete combustion and is found in tobacco smoke as well as...
TSRC, Tob. Sci. Res. Conf., 2012, 66, abstr. 09 An improved method for the determination of selected humectants in tobacco products SODEN C.T.; MARTIN A.; KALATA S.; WILLIAMSON F. Arista Laboratories, Richmond, VA, USA Humectants are an important class of compounds applied to tobacco primarily for the improvement of hydroscopic properties and to act as a carrier for flavor components. For the purposes of this study, we focused on the most prevalent humectants used,...
TSRC, Tob. Sci. Res. Conf., 2012, 66, abstr. 52 Extraction efficiency of selected alkaloids from tobacco products MARTIN A.; WILLIAMSON F. Arista Laboratories, Richmond, VA, USA Nicotine and four minor alkaloids (nornicotine, anabasine, myosmine and anatabine) are compounds synthesized within the tobacco plant and are precursors of the tobacco-specific N-nitrosamines (TSNAs). The accurate quantitation of these compounds is...
TSRC, Tob. Sci. Res. Conf., 2012, 66, abstr. 54 N-Nitrosodiethanolamine in tobacco: method validation and levels present in US tobacco products WILLIAMSON F.; MARTIN A. Arista Laboratories, Richmond, VA, USA N-Nitrosodiethanolamine (NDELA) is a non-volatile nitrosamine classified by the International Agency for Research on Cancer (IARC) as a group 2B carcinogen. It has been identified in both tobacco and tobacco smoke and is currently included on the...
