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: The embodiments of the present invention are directed to applying intimate contact pressures to samples while undergoing ATR infrared interrogation. As a general mode of operation, after a solid sample is placed on the ATR element, a force actuator moves an anvil arm to apply a contact force to the sample against the ATR. Thereafter, when the scan is over, the user can see the result of the one or more scans. The force actuator may be a motor or a solenoid or other type of force actuator. The applied contact force may be a fixed force or may be a user-selectable force or may be automatically controlled through feedback from the spectrometer based on the spectroscopic signature of the sample material.

Abstract: A hand-held spectrometer includes at least one indicator light and a processor configured to control the at least one indicator light to indicate a state of the hand-held spectrometer selected from a group consisting of a background scanning state, a ready-to-scan-sample state, a signal strength state, a fluorescence intensity state, a sample match state, a sample classification state, an error state, a data transfer state, a battery charge state, and a memory capacity state. The sample match state can be, for example, one of a positive match state, a mixture match state, a negative match state, and a match error state. In some embodiments, the error state can be at least one of a background error state, a user error state, and an instrument error state, or any combination thereof.
