| titleOfInvention | Combined gas chromatography mass spectrometry combines the method for gas chromatography determination nicotine purity |
| abstract | The invention discloses a kind of method that combined gas chromatography mass spectrometry combines gas chromatography determination nicotine purity.First by the purity of GC/MS method Preliminary Determination nicotine, then measuring the moisture content in nicotine by GC method, finally by revising the accurate purity obtaining nicotine, correction formula is as follows: NIC%=nic%* (100% wat%).The method, compared with silico-tungstic acid gravimetric method, has simplicity, quick, easily operated, reproducible feature.High to nicotine detection specificity, it is susceptible in sample the interference of other impurity especially alkaline impurities (alkaloid, inorganic base), when the sample being especially long placed in nicotine sample, impurity content is higher carries out purity detecting, easy and simple to handle, separating power is strong, qualitative, quantitative reliable results. |
