Abstract: Described are various embodiments of a system, method and device for laser induced breakdown spectroscopy (LIBS). In some embodiments, the LIBS system comprises a silicon photomultiplier (Si PM) operated in a time-gated photon counting mode. Some such embodiments allow for the provision of a portable LIBS device. Also provided are embodiments for the measurement of constituent carbon, gold and/or other precious metal group elements in a target sample.

Abstract: A method of quantifying at least one property of interest of an oil sands ore sample is provided using a laser-induced breakdown spectroscopy (LIBS) method. The LIBS method may be applied to oil sands ore being conveyed prior to a slurry process to measure oil sand composition and provide information which may predict extraction characteristics. The LIBS method may be applied to oil sands core samples in a laboratory setting to reduce the cost and analysis time associated with conventional laboratory measurement techniques.

Abstract: A method for laser induced breakdown spectroscopy (LIBS) calibration or LIBS assay comprises providing a plurality of reference samples, each having a respective, known concentration of an analyte, assaying each reference sample to obtain a respective LIBS spectrum, and for each reference LIBS spectrum, measuring an intensity of at least one spectral analyte line that varies with concentration of the analyte, and measuring a peak amplitude of at least one saturating line of a reference element. The ratio and known concentrations define a calibration curve for the analyte.
