Patent ID: 8395770

Claim:
A method of providing a chemical analysis of a sample, comprising: (a) supplying a sample to be analyzed; (b) applying ultraviolet excitation radiation from a source directly or indirectly onto the sample to produce emission radiation in the form of Raman emission radiation within a first range of wavelengths and photoluminescence emission radiation within a second range of wavelengths; (c) receiving the emission radiation, directly or indirectly, from the sample at at least one first spectral filter which is capable of passing the Raman emission radiation within at least a portion of the first range of wavelengths along a first optical path; (d) receiving the emission radiation, directly or indirectly, from the sample at at least one second spectral filter which is capable of passing the photoluminescence emission radiation within at least a portion of the second range of wavelengths along a second optical path; (e) measuring an amount of the Raman emission radiation using at least one first detector located directly or indirectly along the first optical path; (f) measuring an amount of the photoluminescence emission radiation using at least one second detector located directly or indirectly along the second optical path; and (g) correlating information concerning the amounts of the Raman emission radiation and photoluminescence emission radiation measured by the at least one first detector and the at least one second detector, respectively, with data associated with one or more chemical compounds of interest to provide at least a partial chemical analysis of the sample.
