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。
