Method of determining the nicotine content of tobacco |
| abstract |
A method of determining on a discrete analyzer the nicotine content of tobacco or a smoking-related product by preparing an aqueous extract of a sample of tobacco or smoking-related product, pre-reacting the extract with an acidic buffered solution of pH not more than 6 for at least two minutes, reacting the pre-reacted extract in the discrete analyzer with aniline and cyanogen bromide, measuring the intensity of yellow coloration generated, and comparing said intensity with that produced by a nicotine standard to determine the nicotine content of said sample. |
