How do you know what you can’t see? This is the challenge many a lab faces as they relentlessly test for novel psychoactive substances (NPS) as unknown samples with an ever-changing ingredient list make discovery difficult work at best. There are many reasons for the complexities of which you can discover in this application note, “Accurate Mass Screening Workflows for the Analysis of Novel Psychoactive Substances.” However, the biggest of which is that non-targeted findings can turn up thousands of molecular features in a single sample. Sifting through the peaks is laborious, and many are normal besides.
Therefore, in this application note, our researchers took a comparative screening approach to NPS by testing urine samples against a control group using high resolution and accurate mass LC-MS/MS. The TripleTOF® system was then operated in IDA mode to acquire MS and MS/MS information simultaneously.Using this method reduced the compound list from thousands to just 10. Now that is a much more manageable sample size for which to analyze peak findings.

In monoclonal antibody (mAb) development, assessment of purity and integrity of the protein in question is critical. CE‑SDS is the gold standard assay and is routinely run from analytical development through QC and lot release. It’s trusted because it consistently delivers quantitative, size‑based insight into purity and fragmentation, and it fits naturally into regulated environments.
In drug discovery and development, Metabolite Identification (Met ID) plays a critical role in understanding biotransformation pathways, ensuring safety, and meeting regulatory requirements. Advanced mass spectrometry techniques have revolutionized this process, particularly through electron-based fragmentation methods such as Electron Activated Dissociation (EAD) and Electron Transfer Dissociation (ETD). While both techniques leverage electron interactions to generate informative fragment ions, they differ significantly in mechanism, performance, and suitability for Met ID workflows.
In analytical laboratories, performance is not optional. Whether supporting regulated pharmaceutical workflows, high-throughput CRO operations, clinical reporting, or food and environmental testing, your mass spectrometry and capillary electrophoresis systems are critical to productivity, compliance, and scientific confidence.
