| titleOfInvention | The cold trap trapping gas chromatography/mass spectrometry detection method of nitromethane in a kind of gaseous phase of main stream smoke of cigarette |
| abstract | The invention discloses the method for nitromethane content in a kind of cold trap trapping Gc/ms Analyser detection gaseous phase of main stream smoke of cigarette.The method is accurate to add nitromethane d using nitromethane in isopropanol dry ice under cryogenic (≤70 DEG C) methanol solvate cold trap trapping gaseous phase of main stream smoke of cigarette 3 Internal standard, sample it is hand it is uniform after, detected using gas chromatograph/mass spectrometer, retention time and abundance of ions are than qualitative, and characteristic ion is quantitative.The present invention is using nitromethane content in gas chromatograph/mass spectrometer accurate quantitative analysis gaseous phase of main stream smoke of cigarette, method is reproducible, and method pre-treatment is simple, easily operation, the rate of recovery is high, is capable of achieving the Accurate Determining to nitromethane content in gaseous phase of main stream smoke of cigarette. |
