One of the most difficult sample analysis for Forensic Toxicologists consist of decomposed tissue samples. This is because fatty materials produced by the decomposition process cause issues for instruments due to their solubility in organic solvents. This issue can easily be over overcome by the use of high quality Solid Phase Extraction (SPE) sorbents.
This is the case recently reported in the Journal of Forensic Sciences by Dr. Mario Giusiani and his team ( Department of Neurosciences, University of Pisa, Italy) who analyzed samples from body that had be missing for over 10 years. Samples of tissue were extracted using UCT's flagship sorbent Clean Screen DAU (ZSDAU020). The team not only identified but also quantified the concentrations of Phenobarbital using GC-MS (without derivatization) in post mortem samples of liver, heart, lung, muscle and skin. This case demonstrates why Clean Screen DAU is the most popular SPE extraction column due to its unmatched analytical performance.
