Abstract

An integrated chemical separation device includes a single device body, a chemical separation unit configured to separate a chemical from a fluid, a Raman sensor substrate comprising one or more surfaces configured to be adsorbed by molecules of the chemical from the fluid, and a Raman scattering spectrometer unit that can emit a laser beam to illuminate the Raman sensor substrate and to detect the chemical from the light scattered from the Raman sensor substrate. The chemical separation unit, the Raman sensor substrate, and the Raman scattering spectrometer unit are held in or mounted to the single device body.
