Abstract: A handheld LIBS analyzer includes a laser source for generating a laser beam and a spectrometer subsystem for analyzing a plasma generated when the laser beam strikes a sample. A nose section includes an end plate with an aperture for the laser beam, a purge cavity behind the aperture fluidly connected to a source of purge gas, and a shield covering the purge cavity. A vent removes purge gas from the purge cavity when the end plate is placed on the sample.

Abstract: A method of and system for detecting the concentration of a target element in a brine wherein the brine is sampled into a container and an aerosol generator is used to generate an aerosol stream of the sampled brine in the container. The aerosol stream may be directed to a collection system. A handheld LIB S device directs a laser beam to the aerosol stream at a location between the aerosol generator and the collection system to generate a plasma. The plasma is analyzed to detect intensity data for a reference element based on the generated plasma and to detect the intensity data of a target element based on the generated plasma. The concentration of the target element in the brine is calculated based on the reference element intensity data and the target element intensity data.

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.

Abstract: An analysis (e.g., LIBS) system includes a source of radiation, an optical emission path for the radiation from the source of radiation to a sample, and an optical detection path for photons emitted by the sample. A detector fiber bundle transmits photons to the spectrometer subsystem. At least one fiber of the fiber bundle is connected to an illumination source (e.g., an LED) for directing light via at least a portion of the detection path in a reverse direction to the sample for aligning, sample presence detection, localizing, and/or focusing based on analysis of the resulting illumination spot on the sample.

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.
