High resolution mass spectrometry is now increasingly used in forensic toxicology laboratories for screening applications. The ability to perform comprehensive and "untargeted" screening enables toxicology laboratories to screen for very large number of compounds in a single analytical run. A particular strength of high resolution mass spectrometers operating in data independent acquisition (DIA) modes such as MSE is the ability to acquire accurate mass spectrometry data on all precursor and fragment ions present in a sample. This enables confident identification of "expected components" by comparison with library data and retrospective investigation of to detect and identify novel psychoactive substances for which standards are difficult to obtain.

For high resolution mass spectrometry to become accessible to the routine toxicology laboratory, powerful and easy to use informatics is essential to process the large volume of data produced and successfully detect and identify components. This webinar will present on the use time of flight technology working in MSE mode and the Waters UNIFI Scientific Information System for targeted, semi targeted and untargeted screening.

What will I learn?

  • How the use of high resolution mass spectrometry can benefit forensic toxicology laboratories for both targeted and non-targeted screening.
  • How UNIFI utilises the inherent power of high resolution mass spectrometry for the detection and identification of illicit drugs, prescribed drugs, OTC drugs, and novel psychoactive substances.
  • How UNIFI utilizes "in silico fragmentation" techniques to identify novel psychoactive compounds for which only limited information is available.
  • How 3D peak detection and componentization improves compound identification.

Who should attend?

  • Forensic toxicology laboratories
  • Drug testing laboratories
  • Institutes of legal medicine
  • Police forensic laboratories
  • State crime laboratories
  • Sports doping laboratories (human and animal doping)
  • Laboratories involved in toxicology research
  • Laboratories interested in detecting novel psychoactive drugs/legal highs

Petur Dalsgaard: Biography

Petur Dalsgaard graduated as a Master of Pharmacy at the University of Copenhagen and then completed his Ph.D. on new metabolites from unexplored fungi at the same institution. This was a joint project between the University of Copenhagen, DTU and the University of Canterbury, New Zealand.
Dr Dalsgaard has over 10 years of working experience with LC/MS on small molecules, and one year post-doctoral experience from the University of Basel working with LC/MS analysis of proteins. Dr Dalsgaard is currently working as a forensic scientist at the Section of Forensic Chemistry at the University of Copenhagen, where he has developed expertise in high resolution mass spectrometry including on UPLC-(Q)TOF-MS and UHPLC-Orbitrap-MS analysis.
Dr Dalsgaard’s primary research areas include screening for drugs in blood, urine and muscle by liquid chromatography/high resolution mass spectrometry and optimised screening for novel psychoactive substances such as synthetic cannabinoids.
