TSRC, Tob. Sci. Res. Conf., 2019, 73, abstr. 058 USP elemental impurities: limit test for metals in nicotine by ICP-MS LOTFI H.; ARROYO M. Global Laboratory Services, Wilson, NC, USA Nicotine included in e-cigarette formulations usually originates as a 90%+ solution, which is purified further prior to use. While the FDA oversees the tobacco industry, there is currently little regulation regarding the quality of raw materials or...
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, Berlin, 2016, Smoke Science/Product Technology Groups, ST 20 The influence of storage conditions and packaging on acetic acid generation in cellulose acetate fibers TATUM C.E.; WILSON S.A.; CASPER R.G.; PEARCE M.J. Eastman Chemical Company, Kingsport, TN, U.S.A. The cellulose acetate polymer used in cigarette filters is made by acetylating wood pulp with acetic anhydride. One advantage of this modified natural polymer is that it readily degrades by multiple mechanisms. While the ultimate products are carbon...
CORESTA Meeting, Agronomy/Phytopathology, 2015, Izmir, Turkey, AP 32 CPA residue levels in consecutive C48 cases of Oriental tobacco WESTBERG H.; SPENCER A. Global Laboratory Services, Wilson, NC, U.S.A. Crop protection agents (CPA) can be applied to tobacco at various stages of the production cycle and if CPA residues are present in the product, they can be topic of concern. After tobacco is processed it is normally packed into cases or bales for...
TSRC, Tob. Sci. Res. Conf., 2015, 69, abstr. 07 Comparison of the cerulean e-cigarette pressure drop testing instrument to the ces 508 cigarette pressure drop and ventilation tester unit for electronic cigarettes, conventional tobacco burning cigarettes, and filter tips AVANTS K.W.(1); WILSON S.A.(2); CLARK J.(1) (1) Liggett Group, LLC, Mebane, NC USA; (2) Eastman Chemical Company, Kingsport, TN USA The pressure drop or “resistance to draw” of cigarettes and cigarette-like products is a prominent experience for consumers. This poster is a comparison of two commercial instruments with different approaches to measuring pressure drop. The...
TSRC, Tob. Sci. Res. Conf., 2015, 69, abstr. 48 Method development and validation of selected metals in e-liquid samples BROWN J. Global Laboratory Services, Inc., Wilson, NC USA Over the past several years, the use of electronic cigarettes and devices has increased. Analysis of Harmful and Potentially Harmful Constituents is at a forefront in both the conventional and electronic cigarette industries. The analysis of various...
TSRC, Tob. Sci. Res. Conf., 2013, 67, abstr. 08 Comparison of auto analyzer methods: discrete vs continuous flow. THURSTON D. Global Laboratory Services, Inc., Wilson, NC, USA Chloride, Sugar, Alkaloids, and Nitrate results were compared using a discrete analyzer and a continuous flow auto analyzer. The new generation discrete analyzers are more automated than the continuous flow auto analyzers. In our initial assessment,...
TSRC, Tob. Sci. Res. Conf., 2013, 67, abstr. 37 Degradable cigarette filters: evaluating TiO2 additives. WILSON S.A.; STEACH J.K. Eastman Chemical Company, Kingsport, TN, USA Cigarette filters are a common litter item which can create a negative visual impact and increase clean-up costs. In the outdoors, the persistence of cellulose acetate-based filters can be reduced by photo degradation with the addition of select TiO2...
CORESTA Meeting, Smoke Science/Product Technology, 2013, Seville, ST 35 The effect of smoke components on the photodegradability of cellulose acetate filters TATUM C.E.; STEACH J.K.; DUNN D.G. Eastman Chemical Company, Kingsport, TN, U.S.A. A current and continued interest in the environmental impact of materials used in consumer products has resulted in the need for an extensive understanding of the degradability of cellulose acetate tow used in cigarette filters. Cellulose acetate...
