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 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...

Research Laboratories, Tennessee Eastman Company, Eastman Chemicals Division, Eastman Kodak Company, Kingsport, TN, USA A new instrument was developed for rapid, semiautomatic analysis of plasticizer in filter rods. Its use entails the spectroscopic determination of plasticizer extracted from filter rods by using an azeotropic Freon TF-methanol solvent. Quantitative...
Tob. Sci., 1981, 25-16, p. 57-60, ISSN. 0082-4523 Spectrophotometric determination of filtration efficiency of cigarette filters SLOAN C. l-l.; CURRAN J.G. Research Laboratories, Tennessee Eastman Company, Eastman Chemicals Division. Eastman Kodak Company, Kingsport, Tennessee 37662. A spectrophotometric method was developed for determining the efficiency of cigarette filters. The method is a modification of one proposed by Smit. The new spectrophotometric method can also be used to determine indirectly the amount of dry...
