Test method for nicotine content in e-liquid or aerosol and method for preparing electronic cigarette e-liquid |
| abstract |
The invention relates to a method for testing nicotine content in e-liquid or aerosol and a method for preparing e-cigarette e-liquid. The method for testing nicotine content in the above-mentioned e-liquid or aerosol comprises the following steps: firstly mixing the sample to be tested with water, then adding an organic solvent immiscible with water for extraction to obtain an aqueous phase solution and an organic phase solution; the sample to be tested It is the aerosol of smoke oil or smoke oil after smoking; the content of bound nicotine in the aqueous phase solution is tested by liquid chromatography; the content of free nicotine in the organic phase solution is tested by gas chromatography. The detection accuracy of the above-mentioned test method is high. |
