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., 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, Aix-en-Provence, 2009, SSPT 32 On-line detection of tobacco smoke constituent by EBEL photo ionisation mass spectrometry: Applications and determination of the photo ionisation cross-sections of relevant compounds ZIMMERMANN R.; ESCHNER M.; BENTE M.; DEUERLING C.; SARAJI M. Helmholtz Zentrum München, Institut für Ökologische Chemie, Neuherberg, Germany and University of Rostock, Analytical Chemistry, Rostock, Germany In the last years a single photo ionisation time-of-flight mass spectrometry (SPI-TOFMS) technology was developed for on-line monitoring of tobacco smoke constituents. One of the main advantages of the SPI-TOFMS approach is the possibility to...
