New paper from the Australian Defense Lab DSTG describing the analysis of three different stock of the nerve agent VX by NMR, LC-HRMS/MS, GC-MS(EI and GC-MS(CI) and identification of impurities that serve as chemical attribution signatures (CAS). The CAS profile contained 44 compounds of which 37 were identified. Several of these compounds could be traced back to the precursor chemicals used for synthesis.
Chemical & Engineering News published an article on the outcomes of the first report of the Investigation and Identification Team (IIT) regarding chemical weapons attacks in Syria. I was asked to comment on how chemistry can point to perpetrators of such attacks. Read the article here.
