No. 39 - Determination of the Purity of Nicotine and Nicotine Salts by Gravimetric Analysis - Tungstosilicic Acid Method

(CRM developed into ISO 13276)

Nov. 1994

CORESTA studies on the tungstosilicic acid method indicate that the most practical and appropriate method for the determination of nicotine purity for samples containing at least 96% nicotine is the described tungstosilicic acid method. Interference due to degradation products at this purity level is negligible.
