Surface-enhanced raman vapor dosimeter
This paper describes a new direct-reading personal dosimeter designed to detect vapors of organic chemicals. The device employs the surfaceenhanced Raman scattering (SERS) technique for direct measurement of the amount of analyte collected on the dosimeter, requiring no sample desorption or wet-chemical extraction procedure. The time-weighted average exposure to the chemical vapors can be determined on the dosimeter substrate. The results with benzoic acid used as the model compound illustrate the usefulness of this SERS-based dosimeter. © 1993 Society for Applied Spectroscopy.
