DIN 10373:2011-05

DIN 10373 specifies a method for the gaschromatographic determination of the nicotine content in tobacco and tobacco products. The ground tobacco samples are extracted under strong alkaline conditions. The nicotine content is determined by gas chromatography in an aliquot of the extraction solution. The nicotine content is calculated after determination of the water content of the tobacco sample on the basis of the dry mass of tobacco used.
