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, Lisbon, 2000, p. 55, AP5 Bulk curing system for small growers BERNARD M.P. Michael Bernard, Stevenage, Herts, UK Most of the world's tobacco is produced in stick barns by small growers, whose inefficient curing causes losses of both weight and quality as well as wasted fuel. The aim of this development was to show that bulk curing for individual crops as small...
Bull. Spec. CORESTA Congress, Lisbon, 2000, p. 103, APOST2 (adjourned) Cost effective solar supplement for Virginia curing BERNARD M.P.; AGUAYO R. Michael Bernard, Stevenage, Herts, UK The objective of this trial was to evaluate the cost effectiveness of a simple means of providing supplementary solar energy for bulk barns. A group of sixteen gas fired barns was used, arranged in two rows of eight under a continuous common roof...
CORESTA Meeting, Agronomy/Phytopathology, Montreux,1997, AP5 EcoCuring System BERNARD M. Michael Bernard, Stevenage, Herts, UK The EcoCuring System is the most energy efficient bulk curing system available, and offers the lowest operating cost. It uses only 30% of the electrical power and 80% of the fuel of comparable bulk barns. It is a continuous system of eight linked...
