Differentiation of new psychoactive substance (NPS), 6-(2-methylaminopropyl)benzofuran (6-MAPB), and its positional isomer, 2-(2-methylaminopropyl)benzofuran (2-MAPB), by means of gas chromatography/mass spectrometry (GC/MS) with quadrupole detection is ambiguous. Reliable distinguishing of the two isomers could be achieved by MS/MS spectra recorded after collision-induced dissociation (CID) of precursor ions. Both electron ionization (EI) and electrospray ionization (ESI) methods could be used for these purposes.
通过带四极杆检测的气相色谱/质谱联用(GC/MS)对新型精神活性物质(NPS)6-(2-甲基氨基丙基)苯并呋喃(6-MAPB)及其位置异构体2-(2-甲基氨基丙基)苯并呋喃(2-MAPB)进行区分存在歧义。通过对前体离子进行碰撞诱导解离(CID)后记录的MS/MS谱图,可以可靠地区分这两种异构体。电子电离(EI)和电喷雾电离(ESI)方法均可用于此目的。
