The measurement of nicotine solutions by means of an ultra-violet colorimeter prerequisites a special procedure because of the solutions being chemically changed during the measuring process already by the low pressure ultra-violet lamp situated beside the cell. The „Einheitliche Vorschriften für die Analyse von Tabak und Tabakrauch“ (prescriptions for the analysis of tobacco and tobacco smoke) being followed until the preparation of the solutions, the verification of the accuracy of the method can be limited to the control of the reproducibility of reading. The results obtained by the procedure in question are compared to those resulting from the silicotungstic method. The experiments indicate that the method is sufficiently accurate for the determination of nicotine in tobacco smoke condensates.
