Simple and rapid screening procedure for 143 new psychoactive substances by liquid chromatography-tandem mass spectrometry.
In recent years, many new psychoactive substances (NPS) from several drug classes have appeared on the drug market. These substances, also known as 'legal highs', belong to different chemical classes. Despite the increasing number of NPS, there are few comprehensive screening methods for their detection in biological specimens. In this context, the purpose of this study was to develop a fast an...
متن کاملNovel psychoactive substances.
There has been a significant increase in the number of new intoxicants on the illegal drugs market globally, also in Norway. The substances are given the name NPS: Novel Psychoactive Substances, and are mainly sold over the Internet. Uncertain dosage of potent substances entails a risk of accidental overdose, and therefore serious intoxication and death. In this article we provide an overview o...
متن کاملHigh resolution mass spectrometry.
Over the past decade, mass spectrometry has been revolutionized by access to instruments of increasingly high mass-resolving power. For small molecules up to approximately 400 Da (e.g., drugs, metabolites, and various natural organic mixtures ranging from foods to petroleum), it is possible to determine elemental compositions (C(c)H(h)N(n)O(o)S(s)P(p)...) of thousands of chemical components sim...
متن کاملDrug metabolite profiling and identification by high-resolution mass spectrometry.
Mass spectrometry plays a key role in drug metabolite identification, an integral part of drug discovery and development. The development of high-resolution (HR) MS instrumentation with improved accuracy and stability, along with new data processing techniques, has improved the quality and productivity of metabolite identification processes. In this minireview, HR-MS-based targeted and non-targ...
متن کاملIdentification of the Related Substances in Ampicillin Capsule by Rapid Resolution Liquid Chromatography Coupled with Electrospray Ionization Tandem Mass Spectrometry
Rapid Resolution Liquid Chromatography coupled with Electrospray Ionization Tandem Mass Spectrometry (RRLC-ESI-MS(n)) was used to separate and identify related substances in ampicillin capsule. The fragmentation behaviors of related substances were used to identify their chemical structures. Finally, a total of 13 related substances in ampicillin capsule were identified, including four identifi...
