    Abstract: A method for determining geochemistry of at least one geological sample with laser-induced breakdown spectral measurements performed on the geological sample in a time variant manner with spectral acquisitions made after each of a plurality of measurement shots, spectral pre-processing performed as necessary, and subsequent analysis is applied to the collected data to determine at least one geochemistry parameter of the sample. The method can provide a rapid method to estimate thermal maturity of a sample, which does not require sample preparation, and which can be non-destructive with respect to portions of the sample. A system for performing the method also is provided.

    Abstract: A LIBS measurement system is described herein that provides an orifice, aperture or opening in a substantially V-shaped chute or sleeve that allows access to the material to be analyzed from the underside of the chute. The laser beam is aimed through the hole and return light (signal) is collected through the hole by a photodetector assembly. A diverter device, which is located at an output end of the chute, diverts certain particles away from the chute upon receipt of an actuation signal.
