Abstract:
1. An integrated chemical separation device, comprising: a single device body; a chemical separation unit configured to separate a chemical from a fluid; a Raman sensor substrate comprising a plurality of nano rods on the Raman sensor substrate or nano holes in the Raman sensor substrate, wherein the plurality of nano rods or nano holes comprise surfaces configured to be adsorbed by molecules of the chemical from the fluid; and a Raman scattering spectrometer unit configured to emit a laser beam to illuminate the molecules adsorbed on the surfaces of the plurality of nano rods or nano holes in the Raman sensor substrate and to detect the chemical from the light scattered from the molecules adsorbed on the surfaces of the plurality of nano rods or nano holes in the Raman sensor substrate, wherein the chemical separation unit, the Raman sensor substrate, and the Raman scattering spectrometer unit are held in or mounted to the single device body.
