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.
