Novel Psychoactive Substances - Certified Reference Materials for Forensic Analysis, Clinical Toxicology & Drug Testing

Importance of the Topic

Novel psychoactive substances (NPS) pose an evolving public health threat due to their rapid emergence, structural diversity, and potential for misuse. Accurate detection and quantitation of these compounds in forensic, clinical, and regulatory settings depend on high-quality certified reference materials (CRMs).

Study Aims and Overview

This document describes a comprehensive portfolio of solution-based CRMs offered by Cerilliant® for NPS analysis. The reference materials cover amphetamines, benzodiazepines, synthetic cannabinoids, cathinones, fentanyls, and other drug classes. The goal is to support forensic laboratories, clinical toxicologists, and pharmaceutical researchers with reliable standards for calibration, quality control, and isotope dilution methods using GC/MS and LC/MS.

Methodology and Used Instrumentation

Certified reference materials are gravimetrically prepared using qualified balances under inert atmosphere and sealed in ampoules for long-term stability. Each CRM undergoes ISO 17034 and ISO/IEC 17025 accredited testing, including homogeneity, stability studies, multi-point calibration curves, and uncertainty assessment.

• Gas chromatography with mass spectrometry (GC/MS) using Equity®-5 and other capillary columns
• Chiral HPLC on Astec® CHIROBIOTIC® V2 column for enantiomeric separation
• Reverse-phase LC/MS with Ascentis® Express RP Amide, Biphenyl, F5 and HILIC columns
• Electrospray ionization tandem mass spectrometry (ESI-MS/MS) for targeted MRM assays

Main Findings and Discussion

• Cerilliant offers over 100 NPS parent drugs, metabolites, labeled internal standards, impurities, and degradants in solution format.
• GC/MS and LC/MS methods demonstrate excellent resolution and sensitivity for diverse NPS classes, including isobaric cathinones and enantiomers of amphetamines.
• Accelerated and real-time stability testing confirms long shelf-lives under inert sealing.
• High-throughput workflows using SPME tip extraction in biological matrices show enhanced analyte recovery and reduced matrix effects.

Benefits and Practical Applications

The ready-to-use solution CRMs simplify method development and routine testing workflows by providing accurate calibrators and controls. They support quantitative analysis, regulatory compliance, and advanced techniques like isotope dilution, thus improving laboratory efficiency and data reliability in forensic, clinical, and pharmaceutical contexts.

Future Trends and Opportunities

Emerging NPS classes such as novel synthetic opioids, designer benzodiazepines, and e-liquid cannabinoids will require continual expansion of reference standards. Advances in high-resolution mass spectrometry, rapid sample-preparation techniques, and automated data analysis promise faster screening and identification of unknown compounds. Customizable CRM kits and digital traceability tools will further enhance laboratory preparedness and regulatory response to the evolving NPS landscape.

Conclusion

The Cerilliant® solution-based certified reference material portfolio represents a robust foundation for accurate and reproducible analysis of novel psychoactive substances. Its broad coverage, rigorous quality control, and compatibility with GC/MS and LC/MS workflows provide essential support for addressing the analytical challenges posed by NPS in forensic, clinical, and research laboratories.
