Abstract: A spectrometer configurable for field analyses of chemical properties of a material is provided. The spectrometer includes: at least one sensor adapted for providing Fourier transform infrared spectroscopy (FTIR) surveillance and at least another sensor for providing Raman spectroscopy surveillance. The spectrometer can be provided with a user accessible instruction set for modifying a sampling configuration of the spectrometer. A method of determining the most likely composition of a sample by at least two technologies using the spectrometer is also provided.

Abstract: A spectrometer system comprising a housing configured as a handheld device with a screen; a source of narrow band illumination; a sensor that detects Raman scattering signals; a source of wide band illumination; an optical element that detect Fourier transform infrared (FTIR) signals; a memory device comprising a library of information with Raman scattering reference information and FTIR reference information; and a processor configured to execute software instructions, wherein the software instructions are configured to: direct the narrow band illumination to the sample; detect the Raman scattering signals; direct the wide band illumination to the sample; detect the FTIR signals; determine a composition of the sample from a similarity between the Raman scattering spectral information and the Raman scattering reference information, and from a similarity between the FTIR spectral information and the FTIR reference information; and display the composition of the sample on the screen.

Abstract: A method of identifying the presence of heroin in an impure heroin composition which contains heroin and at least one fluorescent contaminant which interferes with a Raman signal from the heroin. The method may include contacting the mixture with a solvent such as an alcohol, then contacting the resulting alcohol composition with a SERS surface. The surface may then be exposed to laser light from a hand-held Raman spectrometer to detect a Raman signal from the heroin. An apparatus for performing the method is also provided.
