Abstract
A stationary medium is employed both to separate chemicals from a sample solution and also to generate surface-enhanced Raman scattering, so that spectral analysis of the separated analyte chemical can be performed. Applied driving force causes the sample to flow into the stationary medium and to distribute therethrough, thereby causing rapid separation of the analyte chemical, and surface-enhanced Raman scattered radiation is quickly detected, at a plurality of locations along a flow path defined by the stationary medium, for ultimate analysis.
