Abstract

Seized drug samples were analysed by high resolution QTOF LC-MS/MS to identify new psychoactive substances (NPS). A second-generation component detection algorithm was applied to the untargeted analysis of seized drug samples. The algorithm has been enhanced to reduce the impact of noise artifacts and increase the probability of detecting all ion signals which behave in covariant manner. The untargeted discovery workflow identified putylone and bk-4MA-NBOMe by LC-MS/MS QTOF and confirmed by complimentary techniques including NMR.
