The age of novel psychoactive substances
The emergence of novel psychoactive substances (NPS) on the recreational drug market continues to pose a significant challenge for law enforcement and drug tracking agencies. NPS are a diverse group of synthetic substances designed to mimic the effects of conventionally controlled substances and are often used as adulterants in heroin and counterfeit preparations. NPS vary greatly in potency and purity, often requiring only a small amount to cause acute intoxications. Their increased occurrence in drug cases has resulted in a drastic rise in intoxications and accidental fatalities, posing serious public health risks and legal challenges. As more of these NPS emerge on the illegal drug market, timely screening approaches for accurately detecting and identifying these substances are needed.
LC-MS/MS has become the preferred method for NPS analysis over traditional techniques as it provides the sensitivity, speed and confidence required to reliably identify and quantify NPS and other novel synthetic drugs of abuse present in a variety of complex matrices. Whether you are performing unknown screening to identify novel NPS or quantifying these substances and their metabolites as part of an NPS panel, LC-MS/MS enables both the level of identification confidence and quantification performance with far greater sensitivity and specificity than previously used techniques. Learn about the latest advances in LC-MS/MS instruments, workflows and integrated software solutions from SCIEX for reliable NPS screening, identification, and quantification. The information here will provide you with innovative solutions and comprehensive resources to guide your laboratory toward success with NPS analysis.
Accurate mass solutions for ultimate confidence in NPS characterization
Leverage the power of accurate mass spectrometry as a unique tool to screen and identify new emerging substances with our developed NPS analysis workflows. Gain greater confidence by reliably obtaining comprehensive MS/MS spectral fragment information from biological samples that can be used for identification, confirmation and library matching through our accurate mass platforms. The acquisition of accurate mass data and analyte-specific MS/MS fragment spectra is essentially creating a digital record of the sample. The improvements in selectivity and sensitivity increase confidence in NPS identification and enable retrospective data re-interrogation should new questions or compounds arise in the future.

The full scan MS/MS spectrum obtained can be subsequently matched using an MS/MS spectral library to improve identification confidence. These unique functionalities of the mass analyzer configuration significantly enhance drug confirmation results by minimizing the rate of false negatives and false positives. Additional QTRAP scanning functions such as MS3 (MS/MS/MS) and MRM3 can also be leveraged to significantly reduce matrix and background interferences while providing increased selectivity and sensitivity for challenging workflows. Get the ultimate confidence when reporting your drug confirmation results without compromising the quality of your quantitative data.
