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...
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...
CORESTA Congress, Quebec, 2014, Smoke Science/Product Technology Groups, ST 10 Fine-cut tobacco smoke analysis: learnings from collaborative studies MARX F.P. European Smoking Tobacco Association (ESTA), Brussels, Belgium In the late 1980s, European regulators asked for a measurement method for fine-cut tobacco smoke yields. As a consequence CORESTA decided in 1989 to establish a Task Force in order to study the various issues associated with the use of fine-cut...
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,...
CORESTA Meeting, Smoke Science/Product Technology, 2011, Graz, STPOST 15 Fine-cut tobacco: annual TNCO study using a monitor tobacco blend SCHULZ C.(1); MARX F.P.(2) (1) Imperial Tobacco Group, Reemtsma Cigarettenfabriken GmbH, Hamburg, Germany; (2) European Smoking Tobacco Association (ESTA), Brussels, Belgium ISO Standard 15592-3 has been developed to determine nicotine free dry particulate matter ('tar') and nicotine in mainstream smoke of fine-cut tobacco smoking articles (FCSAs). Regular use of a reference material is recommended to assess if the...
TSRC, Tob. Sci. Res. Conf., 2009, 63, abstr. 10 TSNA method comparison using UHPLC-MS/MS MATHIS J.A.; PO YING YEUNG Global Laboratory Services, Wilson, NC, USA. Method development and optimization was performed for the quantification of tobacco specific nitrosoamines (TSNAs) in tobacco leaf. The objective was to shorten run time and compare the new method to the previous method. The evaluation of method...
CORESTA Meeting, Smoke Science/Product Technology, Jeju, 2007, SSPTPOST 18 A study to assist in the determination of tolerance values to be applied to the analysis of fine-cut smoking articles DYMOND H.F.; WILKES E.B.; KOTZIAS D.; HEBERGER K.; KEPHALOPOULOS S. Consultant, European Smoking Tobacco Association, Southampton, UK The European Smoking Tobacco Association (ESTA) in conjunction with the Joint Research Centre of the European Union (JRC) agreed to a joint experiment to determine the variability of data from routine smoking of fine-cut smoking articles. The study...
