Quantitation of Seven Designer Cathinones in Urine Using Q Exactive Mass Spectrometer

Instrument Type: LCMSMS

Substituted cathinones, or “Bath Salts,” have become the latest abused designer drugs. Based on cathinone, a substance found in the African Catha edulis (khat) plant, substituted cathinones are stimulants with amphetamine- and cocaine-like effects. We describe an HPLC-MS method for the forensic toxicological analysis of the three Schedule I cathinones: MDPV, methylone and mephedrone, as well as other substituted cathinones: methedrone, ethylone, butylone and naphyrone in urine with limits of quantitation (LOQs) of 0.5 ng/mL. For forensic use only.

A Strategy for an Unknown Screening Approach on Environmental Samples Using HRAM Mass Spectrometry

Instrument Type: LCMS

The analysis of food and environmental samples for contaminants by LC-MS has become a quick and cost-effective routine application when run in a targeted fashion, but this method disregards events or circumstances not taken into account beforehand. We describe a method by one data set can serve for routine high throughput quantitative analysis and for versatile non-targeted investigations in a highly automated manner.
