Application of synchronous excitation spectrofluorimetry to drug analysis.

Among the analytical techniques available for the determination of toxic products, fluorimetry is, at present, one of the most frequently employed. But in many cases, measurements at low concentrations are interfered with by Rayleigh and Raman scattering. We propose to eliminate, in great part, this interference and hence increase the sensitivity of the method, by using the new synchronous excitation spectrofluorimetry. Application of this technique to the identification and determination of drugs during recent forensic investigations demonstrates its advantages over classical spectrofluorimetry.
