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...
Tob. Sci., 1970, 14-08, p. 28-30, ISSN.0082-4623 Quantitative determination of nitrate in tobacco using a specific ion electrode JACIN H. Research Division, Morehead Patterson Center, American Machine & Foundry Co., Stamford, Conn., U.S.A. A rapid quantitative procedure for determining nitrate in tobacco stalk, stem and strip is discussed. A nitrate ion-calomel electrode assembly was used. The potential developed was read on an expanded range pH meter. Substances in tobacco that...
