| Fast Forensic Hair Analysis for Drugs of Abuse Using DART Ionization and Orbitrap HRAM |
Hair is a very interesting matrix for forensic investigations: it can be collected less invasively than blood or urine and be stored easily. Not only can hair evidence be used for microscopic comparisons or provide a source of DNA, it also contains traces of used substances such as drugs of abuse, pharmaceuticals and toxicants. In addition, these compounds can be detected with a longer detection window compared to blood and urine. Where drugs of abuse in forensic investigations are conventionally detected using LC- or GC-MS(/MS) methods, recent developments in direct and ambient mass spectrometry have opened up the forensic field to exciting new possibilities. Over the last decade several ambient ionization techniques have been developed, which allow analysis of samples with (almost) no sample preparation. One of these ambient ionization techniques, Direct Analysis in Real Time (DART), has been explored for the analysis of intact locks of hair. The use of DART ionization results in fast analysis without the use of extensive sample preparation or matrix application.

We will present an advanced computational and database framework leading to the much anticipated increase in coverage of toxicologically relevant compounds and their transformation products, taking into account all the important experimental and calculated information necessary for efficient and reliable identifications. Those methods are exploiting combination of library searching methods, both spectral (mzCloud) and structural (PubChem, ChemSpider), with computational techniques like quantum chemical methods, precursor ion fingerprinting, fragment ion search and others.
| An Intelligence Led Approach to the Detection of DoA and Novel Psychoactive Substances |
New Psychoactive Substances (NPS) represent an increasing and ever evolving threat to public health. Traditional analytical approaches to drugs of abuse testing are unable to respond quickly enough to be able to keep up to date with the continually changing NPS situation and are therefore unsuitable for this purpose. The availability of drug intelligence often combined with drug seizures provides the starting point for a new approach to drugs of abuse testing using HRAM. Screening processes continually evolve as new compounds emerge and can be further refined using data from in vitro metabolism and/or positive findings.
| Exhaled Breath Analysis Becomes Easier for more Reliable Drugs of Abuse Testing |
Exhaled breath is an attractive biomatrix for forensic toxicological investigations. Recent findings have demonstrated the potential of using also for nonvolatile components. Human exhaled breath contains aerosol particles in sub micrometer size that are formed from the airway lining fluid. The particles contain typical proteins and lipids from this fluid. A very simple collection device has been constructed to capture the particles in a sampling procedure that is truly noninvasive in nature and only takes 2-3 min to perform. In this webinar Dr Olaf Beck, Lab Director at the Kalorinska Institute, will discuss how this specimen from exhaled breath can be used for analyzing drugs of abuse using the QQQ LC-MS/MS technique.
