Uncertainty of Nicotine of Electronic Cigarette Liquid
In order to improve the accuracy of test results,an analytical method to determine Nicotine in Electronic cigarette liquid was presented by gas chromatography(GC).The results indicated that the main sources of uncertainty were standard solution preparation and standard calibra-tion curve fitting.In addition,the recovery values of this method with 100%is not significant by statistics analysis.When the content of nico-tine is18.3mg/g,in the 95%confidence interval,the expanded uncertainty was1.0mg/g(k=2).
