Abstract
An integrated chemical separation device includes a chemical separation unit configured to separate a plurality of substances in a sample solution, a mixing chamber configured to receive the plurality of substances in the sample solution at different times, a chemical separation and detection controller, and a multi-channel valve configured to direct the plurality of substances in the sample solution to the mixing chamber under the control of the chemical separation and detection controller. The chemical separation and detection controller can introduce nano particles in the mixing chambers to allow each of the plurality of substances to be adsorbed on the nano particles. A Raman scattering spectrometer unit emits a laser beam to illuminate molecules adsorbed on the surfaces of the nano particles and obtains Raman spectra from the plurality of substances.
