| titleOfInvention | Method for measuring diisopropyl naphthalene in cigarette tipping paper |
| abstract | The invention discloses a method for measuring diisopropyl naphthalene in tipping paper for cigarettes, which comprises the steps of taking dichloromethane as an extraction liquid, carrying out oscillation extraction on a tipping paper sample for cigarettes, then transferring the extraction liquid, purifying by a solid phase extraction column, centrifuging a purified liquid, filtering by an organic membrane, and measuring the diisopropyl naphthalene in the tipping paper for cigarettes by adopting a gas chromatography-tandem mass spectrometry combined method. The dilution internal standard method quantitatively avoids the difficulty of quantitative separation and purification of a complex mixture system and also overcomes the influence of matrix effect; the gas chromatography-tandem mass spectrometer is adopted to effectively realize the complete baseline separation of seven isomers of the target object, so that the quantitative accuracy is improved, and the determination result can accurately reflect the content of the target object in the sample; the method adopts direct sample injection, can quickly and accurately detect the content of the diisopropyl naphthalene in the tipping paper for cigarettes, has good repeatability and recovery rate, and is suitable for analysis of large batches of samples. |
