Abstract: Methods and apparatus for laser induced breakdown spectroscopy (LIBS) sample chamber. An apparatus includes a sample chamber, a laser source connected to an excitation optics assembly, the excitation optics assembly connected to a first port on the sample chamber, a collimator assembly connected to a spectrometer, the collimator assembly connected to a second port on the sample chamber, and a first lens tube positioned on the first port and a second lens tube positioned on the second port, the first lens tube protecting the first port connected to the excitation optics assembly and the second lens tube protecting the second port connected to the collimator assembly from particles emitted when a laser pulse from the laser source ablates a surface of a target sample and generates a plasma.

Abstract: Devices and methods are disclosed that allow for analysis with simplified sample preparation. Of particular relevance is the analysis of wire samples (e.g., weld wires) using laser induced breakdown spectroscopy (LIBS) or optical emission spectrometry (OES). Representative devices can isolate a sample, such as in a sealed, inert environment in an analytical instrument. These devices may include first and second sample end attachments connected to a body, which has a connecting portion that may be configured for alignment with the face of the instrument. The body may also include a rotatable cap, and the sample end attachments may be joined to this cap (e.g., at opposite ends thereof) to allow adjustment of the angular position of the sample, relative to the connecting portion, which in use may be affixed to the instrument.

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).
