Zusammenfassung: | The invention discloses a determination method of diisopropyl naphthalene in cigarette tipping paper. Methylene dichloride is used as extraction liquid; a cigarette tipping paper sample is subjected to oscillation extraction; then, extraction liquid is transferred; after the purification by a solid-phase extraction column, filtering is performed through an organic film; the diisopropyl naphthalene in the cigarette tipping paper is determined by a gas chromatography-tandem mass spectrometry combined use method. The dilution inner marking method quantificationally avoids the quantitative separation and purification difficulty of a complicated mixture system; the substance effect influence is overcome; a gas chromatography-tandem mass spectrometry combined use instrument is used for effectively realizing the complete separation of a base line on seven kinds of isomers of a target; the quantitative accuracy is improved; the determination result can accurately reflect the target content in the sample.
