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...

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. 17 Quantitative determination of volatile nitrosamines in smoke using gas chromatography-mass spectrometry. GRISSOM D.B.; STEELMAN D. Lancaster Laboratories, Inc., Winston Salem, NC, USA Lancaster Laboratories has done previous work which includes the analysis of VNA in smokeless and alternative tobacco products, carried out by GC/MS/MS. Although acceptable results have been ascertained using this GC/MS/MS method, routine testing of...
TSRC, Tob. Sci. Res. Conf., 2013, 67, abstr. 27 Determination of coumarin in tobacco and alternative tobacco products. QIAN N.; WILKINS J. Lancaster Laboratories Inc., Lancaster, PA, USA A sensitive UPLC-UV method was developed, optimized and validated for the analysis of coumarin (2H-1-benzopyran-2-one) in tobacco blends and various alternative tobacco products (ATP). The validation parameters included precision/intermediate...
TSRC, Tob. Sci. Res. Conf., 2012, 66, abstr. 19 Determination of beryllium, chromium, cobalt, nickel, arsenic, selenium, cadmium, mercury, lead in tobacco and tobacco products by inductively coupled mass spectrometry. STOGNER D.; BENNER D. Lancaster Laboratories, Winston-Salem, NC, USA The ICP-MS combines a high temperature heat source with a mass spectrometer to convert atoms of elements to ions, which are separated and detected according to their atomic masses. This presentation describes a method for determining the elemental...
TSRC, Tob. Sci. Res. Conf., 2012, 66, abstr. 20 Validation of new smoking system for detection of nitrogen oxides FRYE R.(1); URBAN D.(2); ALLEN D.(1) Lancaster Laboratories, Winston-Salem, NC, USA; (2) Lancaster Laboratories, Lancaster, PA, USA The need for increased efficiency and throughput in determination of nitrogen oxides in mainstream smoke brought the Cerulean SM450N smoking machine to the forefront. A validation protocol was designed to evaluate the SM450N 20-port linear smoking...
