Abstract
An embodiment of a laser induced breakdown system is described that comprises a portable device that includes: a laser configured to produce a beam comprising a plurality of repeating pulses; a processor configured to open a data acquisition window after a delay period, wherein the delay period begins upon production of one of the pulses; one or more optical elements configured to direct the beam at a sample and collect emitted light from a plasma continuum; and an optical detector configured to produce a plurality of signal values from the emitted light from the plasma continuum collected during the data acquisition window, wherein the processor is configured to identify an element from the signal values.
