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. 051 Evaluation of filter density vs filter pressure drop for characterizing cellulose acetate filters NORFLEET K.R.; ROBERTSON R. Celanese Corporation, Narrows, VA, USA The consideration of filter density as a filter design parameter has increased in recent years. Traditional filter design is based on pressure drop or resistance to draw to achieve specified smoke filtration levels (example NFDPM). Pressure drop is...
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, STPOST 21 (also presented at TSRC 2016) Puff-by-puff tar, nicotine and carbonyl profiles under different smoking regimens of commercial cigarettes with various carbon filter technologies ROBERTSON R.M.; NORFLEET K.; CANTERBURY W.B. Celanese, Narrows, VA, U.S.A. Puff-by-puff smoke analysis has shown that the CelFX® carbon filter technology has similar nicotine and tar smoke delivery profiles but with significantly reduced carbonyls, particularly in the first 6 puffs, compared to a cellulose acetate filter....

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...
CORESTA Meeting, Smoke Science/Product Technology, 2015, Jeju, ST 48 CelFX™ carbon technology: puff-by-puff profile ROBERTSON R.M.; SUTHAR J.N.; BASU S. Celanese, Narrows, VA, U.S.A. CelFX™ carbon filter technology has been shown to reduce vapor phase smoke components by 40-90% in prior work[1]. In order to expand the understanding of this filtration performance, this work will evaluate the puff-by-puff machine profile to assess...
CORESTA Meeting, Smoke Science/Product Technology, 2015, Jeju, STPOST 18 Particle breakthrough comparison of commercial carbon filters with CelFX™ carbon/acetate filters ROBERTSON R.M.; SUTHAR J.N.; BASU S. Celanese, Narrows, VA, U.S.A. Previous works have evaluated cigarette filter carbon particle release from various filter designs. The recently introduced CelFX™ Matrix Technology offers high loadings of carbon, with low pressure drops and has not been studied for the particle...
