Abstract: A spectrometry device is a spectrometry device for measuring measurement target light emitted from a sample, including: an integrating sphere which includes an inner wall surface and an attachment hole; an adapter which includes a guide hole guiding the measurement target light and is disposed in the integrating sphere; a plate which includes a first surface covering the guide hole from the outside of the integrating sphere and allowing the sample to be mounted thereon and a second surface and through which the measurement target light is transmitted; a holder which includes a concave portion mounting the plate thereon and is attached to the attachment hole; and a spectral detector which detects the measurement target light. The concave portion includes a bottom surface facing the second surface and a side surface surrounding the periphery of the plate. The bottom surface and the side surface are coated with a reflective material reflecting the measurement target light.

Abstract: A Laser Induced Breakdown Spectrocopy (LIBS) system for the analysis of a sample pellet of a consolidated granular material retained in a tubular container may include a laser source configured to emit a pulsed laser beam towards an exposed surface of the sample pellet; and a sample station configured to hold the cylindrical tubular container in one or more orientations to present an exposed surface of the sample pellet towards the pulsed laser beam. The sample station may induce linear movement of the sample pellet along an axis and to expose a portion of the outer side surface of the sample pellet previously constrained through contact with an inner surface of the cylindrical tubular container. The sample station may induce rotational motion of the outer side surface of the sample pellet around the movement axis to present the portion of the outer side surface as the exposed surface.

Abstract: Methods and apparatuses for direct multiplication Fourier transform millimeter wave spectroscopy are disclosed herein. A sample method includes generating at least one pulse of microwave electromagnetic energy. The sample method also includes frequency-multiplying the pulse(s) to generate at least one frequency-multiplied pulse and filtering at least one spurious harmonic of the frequency-multiplied pulse to generate at least one filtered pulse. The spurious harmonic is generated by frequency-multiplying the pulse. The method also includes exciting a sample using the filtered pulse. The method further includes detecting an emission from the sample. The emission is elicited at least in part by the filtered pulse.
