Green Analytical Toxicology procedure for determination of ketamine, its metabolites and analogues in oral fluid samples using DLLME

Este estudo teve como objetivo desenvolver um método analítico para determinação de cetamina, seus metabólitos (norcetamina e 6-hidroxi-norcetamina) e seus análogos (2-fluorodesclorocetamina e desclorocetamina), utilizando DLLME e LC-MS/MS, e seguindo o conceito de toxicologia analítica verde.

Development and validation of quantitative analytical method for 50 drugs of antidepressants, benzodiazepines and opioids in oral fluid samples by liquid chromatography–tandem mass spectrometry

Abstract Purpose We developed and validated a method for quantitative analysis of 50 psychoactive substances and metabolites (antidepressants, benzodiazepines and opioids) in oral fluid samples using simple liquid–liquid extraction procedure followed by liquid chromatography–tandem mass spectrometry (LC–MS/MS). artigo completo: https://link.springer.com/article/10.1007/s11419-020-00561-8

Green analytical toxicology method for determination of synthetic cathinones in oral fluid samples by microextraction by packed sorbent and liquid chromatography–tandem mass spectrometry

We developed and validated a method for quantitative analysis of ten synthetic cathinones in oral fluid (OF) samples, using microextraction by packed sorbent (MEPS) for sample preparation followed by liquid chromatography‒tandem mass spectrometry (LC‒MS/MS). OF samples were collected with a Quantisal™ device and 200 µL was extracted using a C18 MEPS cartridge installed on a […]
