FLT #11: From Screening to High Confidence Quantitation: A QTOF Workflow for Comprehensive Drug Analysis in Forensic Toxicology
In this webinar, Dr. Krotulski presents a comprehensive LC–MS workflow for the analysis of kratom and its alkaloids using the SCIEX X500R QTOF system. The session highlights a high-resolution approach that enables both qualitative identification and quantitative measurement on a single platform, addressing the need for reliable and efficient detection of kratom-related compounds across forensic and clinical settings.
The method leverages the accurate mass and SWATH® acquisition capabilities of QTOF technology to characterize key kratom alkaloids in complex matrices. Dr. Krotulski will discuss his approach to blood analysis, including sample preparation, acquisition strategies, and data interpretation for confident compound identification and measurement. The same workflow is also applied to commercially available smoke shop products, demonstrating how the method can be used to evaluate product variability and composition.
A key component of the workflow is the use of defined cutoff thresholds to support reporting, enabling laboratories to apply consistent decision criteria while maintaining analytical rigor. By combining screening and quantitation capabilities on a single SCIEX X500R system, this approach offers flexibility and operational efficiency without requiring multiple platforms.
Attendees will gain practical insight into implementing LC–MS QTOF-based kratom analysis, with a focus on improving confidence in results and adapting to evolving testing demands in toxicology and drug monitoring.
