I personally monitor over 200 blogs each and every day in real time using […]
Emerging Science: Dried Blood Spot Analysis in Toxicology
Dried Blood Spot (DBS) or Dry Plasma Spot (DPS) analysis as applied to forensic analytical chemistry (toxicology) for Drugs of Abuse testing is an emerging science that there has been some recent activity in the peer reviewed literature. This post will examine this emerging technology and evaluate the benefits and the limitations of this assay. […]
The Forensic Science of the identification of Osama bin Laden
The Forensic Science of the identification of Osama bin Laden President Barack Obama announced yesterday (5/1/2011) that Osama bin Laden had been killed. As historic and newsworthy as that event is, this post isn’t about that event. Instead, this post is about the technology and the science mostly likely used that lead to the confident […]
Why doesn’t your state crime laboratory use AMDIS?
I have written about chromatography, gas chromatography (GC) and even gas chromatography with mass spectrometry (GC-MS). Here they are (in no particular order): GC-MS is not perfect: The case study of methamphetamine Why do I see two peaks on my EtOH analysis using HS-GC-FID? What is the difference between HS-GC-FID and GC-MS? Drugs of Abuse (DOA) […]
