A flow injection trace gas analyzer for on-site determination of organoarsenicals
Lewisite was developed during World War I as a chemical warfare agent. Several countries produced large quantities of the agent before, during and after World War II. The Chemical Weapons Convention treaty, recently signed, requires the destruction of Lewisite. In implementing the Chemical Weapons Convention treaty, it will be necessary to monitor the facilities at which various chemical agents including Lewisite may be stored for compliance with the agreement. The inspection procedures must meet stringent standards for safety, quality assurance and accountability. In preparing for these inspections a technology gap has been identified in the ability to detect and monitor for the presence of Lewisite in ambient air, particularly in the facilities where chemical warfare agents are stored. A method and an apparatus for determining the concentration of Lewisite in the ambient atmosphere are described. The apparatus includes a mechanism for separating and collecting a Lewisite sample from the atmosphere, a mechanism for converting the collected Lewisite to an arsenite ion solution sample, and a mechanism for electrochemically detecting the converted arsenite ions in the sample, whereby the amount of arsenite ions detected is proportional to the concentration of Lewisite in the atmosphere.
