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 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...
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., 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...
Bull. Spec. CORESTA Congress, Jerez de la Frontera, 1992, p. 99, ST25, ISSN.0525-6240 Rheology of homogenized tobacco DE VOS J. Tamag Basle Ltd., Birsfelden, Switzerland. We offer a process for the production of homogenized tobacco sheet from offals such as stems, scraps and dust. In preparation for the sheet forming step, the ground tobacco waste is compounded with an aqueous binder dispersion to an extrudable dough;...
Bull. Spec. CORESTA Symposium, Taormina, 1986, p. 97, T05, ISSN.0525-6240 Some chemical and technical possibilities to increase the filling power of tobacco sheet EGRI L.; NAIR G. Tamag Basle Ltd., Birsfelden, Switzerland. The filling power of the tobacco sheet produced by roller system shows generally lower values than the filling power of the tobacco sheet produced by slurry or paper system. In order to exploit the advantage of the low water and energy requirement of...
Bull. Spec. CORESTA Congress, Vienna, 1984, p. 58, T02, ISSN.0525-6240 Influence of certain production parameters of sheet tobacco on its physical and smoke analytical values EGRI L.; REHAK J.; NAIR G. Tamag Basle Ltd., Birsfelden, Switzerland. Production of sheet tobacco from tobacco waste by means of deformation tools with difference velocity (slurry, roller, extruder etc.) results in different physical properties of the sheets parallel and transverse to the direction of the belt....
