What to know about Institutional Prestige

Researchers at Lawrence Livermore National Laboratory's Forensic Science Center have developed a new analytical method to detect pinacolyl alcohol, a marker for the nerve agent Soman. This technique allows for the detection of the marker using both gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry, enhancing the evidentiary capabilities for chemical weapons investigations.

A new capability to detect chemical weapons involves two existing methods Stephanie Baum Scientific Editor Robert Egan Associate Editor In the aftermath of suspected chemical attacks, investigators from the Organization for the Prohibition of Chemical Weapons…

Why it matters

Thorough forensic laboratory analysis of these samples is essential for proving what—if any—chemical agents were used and verifying their identities.

Common ground

Researchers at Lawrence Livermore National Laboratory's (LLNL) Forensic Science Center (FSC) recently developed a new technique to detect pinacolyl alcohol (PA), a unique marker for the nerve agent Soman in environmental samples.
