About
Petur Weihe Dalsgaard is a prominent forensic toxicologist whose research has significantly advanced the detection and quantification of illicit and medicinal drugs in biological matrices. Working at the intersection of analytical chemistry and forensic science, Dalsgaard has made substantial contributions to developing high-throughput, sensitive screening methodologies that are now integral to modern toxicological investigations. His most influential work centers on leveraging cutting-edge mass spectrometry techniques, particularly ultra-high-performance liquid chromatography coupled with time-of-flight mass spectrometry (UHPLC-TOF-MS). A landmark 2013 study introduced a fully automated solid-phase extraction (SPE) system capable of screening 256 analytes in whole blood simultaneously, garnering 78 citations and setting a new benchmark for comprehensive forensic drug screening. A companion study that same year demonstrated precise quantification of 31 drugs and metabolites, earning 77 citations from the forensic community. Dalsgaard's 2017 investigation into fentanyl analogues—accumulating 70 citations—addressed an urgent public health crisis by developing retrospective screening capabilities for 50 fentanyl-related compounds, directly supporting overdose investigations. Collectively, his work has equipped forensic laboratories worldwide with robust, efficient analytical tools, making him a key figure in the evolution of modern forensic toxicology.
