Abstract: In the operation of analytical devices, and particularly laser induced breakdown spectroscopy (LIBS) devices, a number of advantages may be obtained by the use of complementary safety mechanisms, such as those that govern the operation or firing of a laser. Such complementary safety mechanisms, compared to the individual safety mechanisms acting alone, prevent operation of the laser under a greater number of unsafe circumstances (even if one or more detected conditions are safe, based on not activating the associated safety mechanism) and permits operation under a greater number of safe circumstances (even if one or more detected conditions are unsafe, based on activating the associated safety mechanism).

Abstract: A hand-held spectrometer includes at least one indicator light and a processor configured to control the at least one indicator light to indicate a state of the hand-held spectrometer selected from a group consisting of a background scanning state, a ready-to-scan-sample state, a signal strength state, a fluorescence intensity state, a sample match state, a sample classification state, an error state, a data transfer state, a battery charge state, and a memory capacity state. The sample match state can be, for example, one of a positive match state, a mixture match state, a negative match state, and a match error state. In some embodiments, the error state can be at least one of a background error state, a user error state, and an instrument error state, or any combination thereof.
