Analysis of “Bath Salt” Compounds from Urine for Forensic Toxicology Using μElution Mixed-mode SPE Combined with UPLC/MS/MS Detection

7 Feb 2014

This application note details a strategy for the successful extraction and analysis of representatives of several different classes of synthetic cathinones from human urine samples for forensic toxicology. Using mixed-mode solid phase extraction (SPE) followed by UPLC/MS/MS analysis, a panel of 10 synthetic cathinones was extracted with excellent recovery and analytical sensitivity.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.

Analyzers, immunoassays and drugs of abuse test kits and presumptive test kits are an essential aspect of toxicology investigation.UrineThe analysis of urine is important in medicinal, anti-doping, forensic and life sciences applications. The ability to evaluate what someone has ingested through their urine enables fast detection and diagnosis of certain illnesses. Forensic ToxicologyForensic toxicology is used to determine cause of death, drug use and contaminations. Toxicological evaluations are commonly used in analytical chemistry, clinical, life sciences and forensics.
