1 Scope

This standard specifies the stable isotope ratio of hydrogen in the nicotine, a characteristic component of tobacco, by gas chromatography-stable isotope ratio mass spectrometry. method. This standard applies to tobacco and tobacco products, electronic cigarette smoke, smokeless tobacco products and other samples of tobacco characteristic components nicotine hydrogen stable For the determination of the isotope ratio, the gum base type tobacco product can be used as reference.

2 Normative references

3 Principle

The nicotine in the target sample is freed out using an aqueous solution of sodium hydroxide, and then liquid-liquid extraction with n-hexane is carried out by gas chromatography- Determination of the stable isotope ratio of nicotine in the extract by pyrolysis-stable isotope ratio mass spectrometry (GC-HTC-IRMS), and then The true value and measured value of the reference material are known to correct the nicotine hydrogen stable isotope ratio in the sample.
