Surface Plasmon Resonance Spectroscopy-Based Process Sensors

[摘要] The Analytical Development Section (ADS) of the Savannah River Technology Center (SRTC) developed a novel, monolithic surface plasmon resonance (SPR) probe for process monitoring as part of the Defense Programs Plant Directed Research and Development Program. The sensor incorporates multi-layer thin films on a fused-silica hemispherical lens. The simple optical design of the device increases robustness and fabrication precision and allows for sensitive SPR measurements to be made without complex polarizing and collimating optics. The utility of the probe is demonstrated for sensing moisture and hydrogen in process environments. Theoretical optical modeling of the SPR system and room temperature performance characteristics of the sensor are reported.
