Abstract
Overview
ISO 15152:2003 - "Tobacco - Determination of the content of total alkaloids as nicotine - Continuous-flow analysis method" - specifies a laboratory procedure to quantify total alkaloids expressed as nicotine in manufactured and unmanufactured tobacco using a . The method uses an aqueous (or 5% acetic acid) extract of ground tobacco, chemical derivatization with sulfanilic acid and , and colorimetric detection at to determine nicotine-equivalent alkaloid content.
