Described are various embodiments of a system, method and device for laser induced breakdown spectroscopy (LIBS). In some embodiments, the LIBS system comprises a silicon photomultiplier (Si PM) operated in a time-gated photon counting mode. Some such embodiments allow for the provision of a portable LIBS device. Also provided are embodiments for the measurement of constituent carbon, gold and/or other precious metal group elements in a target sample.

Laser-induced breakdown spectroscopy system and method, and detection system and method therefor

Disclosed are circuits for automatic calibration of the gain of electronic amplification and digitization systems for use with X-ray detectors. The calibration is based on injecting predetermined pulses into the electronic system and deriving a calibration ratio based the digital value of their amplitude with the digital value of the same pulses, unamplified and digitized with a high accuracy reference ADC. All ADCs, as well as the DACs used to control the pulser amplitude are referenced to a single common reference voltage. Calibration for non-linearity of the gain is disclosed with an alternative embodiment for the same circuits.

Method and apparatus for X-ray detection system gain calibration using a pulser

Herein disclosed is an x-ray florescence (XRF) test system which comprises an XRF test instrument used for testing a test target's responses to X-rays, the instrument including a test window allowing the X-ray and its responsive energy to pass through, and a window protecting film assembly allowing X-rays to pass through and providing protection to the window, the film assembly being configured to be coupled with the window in a fashion to be removed from or applied or reapplied over the window. The corresponding calibration mode can be manually or automatically applied according to the specific film assembly presently in use. An embodiment of the film assembly comprises a thin film fixed with an adhesive layer to a supporting frame having a closely spaced array of apertures.

XRF instrument with removably attached window protecting film assembly

An XRF system including an analyzer with a sample bottle holder, an x-ray source positioned to emit x-rays into a sample bottle placed in the holder, and a detector positioned to receive x-rays emitted by a sample in the sample bottle positioned in the sample bottle holder. A supply of sample bottles receivable in the sample bottle holder, each sample bottle including a first cap with the window therein for allowing x-rays to pass there through when the sample bottle is positioned in the holder, and a second cap without a window for transporting and storing the sample.

XRF system with novel sample bottle

A dual source tube XRF system and method wherein a first x-ray source is employed to direct x-rays in a first energy band at a sample and at least a second x-ray source is employed to direct x-rays in a second energy band at the sample. A detector is responsive to x-rays emitted by the sample after irradiation by the first and second x-ray sources. An analyzer is responsive to the detector and is configured to determine the amount of at least a first substance in the sample based on irradiation of the sample by the first x-ray source and to determine the amount of at least a second substance in the sample based on irradiation of the sample by the second x-ray source. A controller is responsive to the analyzer and is configured to energize the first and second x-ray sources either simultaneously or sequentially.

Dual source XRF system

A fuel analysis system and method wherein an x-ray source emits x-rays at an energy level below but proximate the absorption edge of sulfur. A monochromator is in the optical path between the source and a fuel sample for directing x-rays at a single energy level at the fuel sample to limit excitation of any sulfur in the fuel sample. A detector is responsive to x-rays emitted by the sample and an analyzer is responsive to the detector and configured to determine the amount of silicon and aluminum in the sample.
