Abstract:

Solid phase microextraction SPME is used to conduct analyses for trace levels of nerve agent. Measurements can be improved by using a SPME polymer coating that is selective for nerve agents in place of current commercial polymers. This research focuses on three hydrogen bond acidic polymers developed by the Naval Research Laboratory that have an increased affinity for nerve agents. These polymers were coated onto fused silica fibers using three methods dip coating, applicator coating, and ink jet coating. Vapor and aqueous phase sampling of nerve agent simulant was conducted to evaluate the performance of these polymers. The hydrogen bond acidic polymers showed significantly higher uptakes than commercial polymers and were able to detect vapor phase nerve agent simulant at 0.005 mgm3 for a 1 minute sample and aqueous phase simulant at 1 ppm for a 10 minute sample. The use of these polymers with SPME extraction has the potential to provide rapid field sampling for the detection of trace levels of nerve agent.
