Chemical threat agents (CTAs) such as highly toxic industrial chemicals and chemical warfare agents pose a serious threat to national security.  In the event that a CTA is used in a crime or act of terrorism, there will be a need to provide evidence for attribution.  Pacific Northwest National Laboratory is developing and evaluating approaches for the discovery and exploitation of trace impurities and constituents as chemical attribution signatures (CAS).  Our presentation will cover recent developments in the discovery of chemical attribution signatures for CTAs studied by our group. In particular, we will discuss our evaluation of several preprocessing software tools for locating potential CAS in gas chromatography/mass spectrometry data.  In addition, we will discuss our recent efforts in matching chemical agents to their starting materials using trace impurities.
