Surface-Enhanced Raman Vapor Dosimeter

Not Accessible

Your library or personal account may give you access

Abstract

This paper describes a new direct-reading personal dosimeter designed to detect vapors of organic chemicals. The device employs the surface-enhanced 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.
