Abstract: LIBS measurement systems are disclosed that are configured to monitor a temperature of a molten metal sample (10) during cooling of the molten metal sample in a crucible (20), and to initiate a LIBS measurement after the temperature of the molten metal sample satisfies measurement temperature criteria. The system may also monitor the temperature of an empty crucible to assist in ensuring that the crucible temperature is (i) sufficiently high to ensure that after the molten metal sample is delivered to the crucible and cools to satisfy the measurement temperature criteria, a sufficiently low cooling rate of the molten metal sample occurs during the LIBS measurement, and (ii) optionally sufficiently low to avoid an unnecessarily long cooling time of the molten metal sample prior to satisfying the measurement temperature criteria and initiation of the LIBS measurement. The LIBS measurement system may be mobile and battery-powered, and may include an integrated calibration station (500).
