Abstract: A combined handheld XRF and LIBS system and method includes an XRF subsystem with an X-ray source operated at a fixed medium voltage and configured to deliver X-rays to a sample without passing through a mechanized filter and a detector for detecting fluoresced radiation from the sample. The LIBS subsystem includes a low power laser source for delivering a laser beam to the sample and a narrow wavelength range spectrometer subsystem for analyzing optical emissions from the sample. The X-ray source is operated at the fixed medium voltage to analyze the sample for a first group of elements, namely, transition and/or heavy metals. The low power laser source is operated to analyze the sample for a second group of elements the XRF subsystem cannot reliably detect, namely, C, Be, Li, Na, and/or B, and to analyze the sample for a third group of elements the XRF subsystem cannot reliably detect at the fixed voltage, namely, Al, Si, and/or Mg, or where the XRF subsystem would require higher tube voltage, namely Cd, Ag, In, Sn, Sb, and/or Ba; and/or rare earth elements.

Abstract: A LIBS analyzer, preferably handheld, includes a laser configured to produce a plasma on a sample and a spectrometer responsive to radiation emitted from the plasma and configured to produce a spectrum. A controller subsystem is configured to control energizing the laser and to analyze the resulting spectrum from each laser pulse to determine if the laser is aimed at a sample. If the analyzed spectrum reveals the laser is not aimed at the sample, the controller subsystem halts the laser puke sequence.

Abstract: A handheld LIBS spectrometer includes an optics stage movably mounted to a housing and including a laser focusing lens and a detection lens. One or more motors advance and retract the optics stage, move the optics stage left and right, and/or move the optics stage up and down. A laser source in the housing is oriented to direct a laser beam to the laser focusing lens. A spectrometer subsystem in the housing is configured to receive electromagnetic radiation from the detection lens and to provide an output. A controller subsystem is responsive to the output of the spectrometer subsystem and is configured to control the laser source and motors. In this way, auto-calibration, auto-clean, and auto-focus, and/or moving spot functionality is possible.

Abstract: A portable hand held XRF analyzer and method wherein an X-ray source directs X-rays to a sample and a detector detects photons emitted by the sample. A controller subsystem controlling the X-ray source an I/O section and is responsive to the detector and I/O section. The controller subsystem is configured to present to the user, via the I/O section, a choice to invoke an aluminum alloy algorithm test. An aluminum alloy algorithm test is invoked if the operator chooses the aluminum alloy algorithm test. Then, the X-ray source is operated at a predetermined voltage level and predetermined current level and the detector output is analyzed to determine elements and their concentrations present in the sample. Preferably, if the analysis fails to detect one or more common aluminum alloy elements present in the sample and/or fails to specify a particular aluminum alloy, then the X-ray source is automatically operated at a higher voltage and lower current level to repeat the analysis step.
