The invention relates to a high performance liquid chromatography-tandem mass spectrometry method for measuring TSNAs (tobacco-specific nitrosamines) in electronic cigarette smoke, which belongs to the technical field of physical and chemical inspection of an electronic cigarette. The method is characterized by comprising the steps: sucking an electronic cigarette sample by virtue of a smoking machine, trapping the electronic cigarette smoke by adopting a full-smoke trapping device, adopting a Cambridge filter to be serially connected with an absorption bottle, independently adopting the Cambridge filter or independently adopting the absorption bottle, measuring the smoke by adopting a high efficiency liquid phase chromatography-triple quadrupole tandem mass spectrograph, and quantifying analyte by adopting an internal standard method. The method is a brand new method for measuring the content of TSNAs in the electronic cigarette smoke. The method is good in selectivity and accuracy.
