Paper Abstract

A new class of fiber optic chemical sensor is presently under development at the Pacific Northwest Laboratory. The new probe type, termed fiber optic spectrochemical emission sensor (FOSES), implements either electrical spark or radio frequency excitation (via helium plasma) of analyte species at the probe tip for remote in situ detection. The two excitation modes offer complementary chemical detection methods suitable for vapors, aerosols, or liquid samples. The new probe concept offers the potential for multi-point real-time field sampling and mapping of groundwater contamination plumes or airborne chemical contamination. This paper addresses probe designs, probe characteristics and performance, detection limits, and future concepts for multi-point sampling systems.
