Abstract: Apparatus for laser induced ablation spectroscopy (LIBS) is disclosed. An apparatus can have a computer, a pulsed laser and a lightguide fiber bundle that is subdivided into branches. One branch can convey a first portion of the light to a first optical spectrometer and a different branch can convey a second portion of the light to another optical spectrometer. The first spectrometer can be relatively wideband to analyze a relative wide spectral segment and the other spectrometer can be high dispersion to measure minor concentrations. The apparatus can have a plurality of spectrometers with distinct and/or complementary capabilities, and can include an inductively coupled plasma mass spectrometer and data and instructions in tangible media operable to obtain a synergistic composition analysis based on optical spectra and ion mass to charge ratio peaks from the mass spectrometer.

Abstract: Methods for laser induced ablation spectroscopy (LIBS) are disclosed. Light from laser ablation can be gathered into a lightguide fiber bundle that is subdivided into branches. One branch can convey a first portion of the light to a broadband spectrometer operable to analyze a relatively wide spectral segment, and a different branch can convey a second portion of the light to a high dispersion spectrometer operable to measure minor concentrations and/or trace elements. Emissions can be analyzed using a plurality of spectrometers having distinct and/or complementary capabilities, and with a synergistic method using inductively coupled plasma mass spectrometry.

Abstract: Methods for laser induced ablation spectroscopy are disclosed. A position sensor, and position motors can move a sample stage in three independent spatial coordinate directions, and a stage position control circuit can move an analysis sample site to selected coordinate positions for ablation. Light from laser ablation can be gathered into a lightguide fiber bundle that is subdivided into branches. One branch can convey a first portion of the light to a broadband spectrometer operable to analyze a relatively wide spectral segment, and a different branch can convey a second portion of the light to a high dispersion spectrometer operable to measure minor concentrations and/or trace elements. Emissions can be simultaneously analyzed in various ways using a plurality of spectrometers having distinct and/or complementary capabilities, and isotope analysis of a sample can be performed.

Abstract: Chemical composition of liquid phase samples is determined based on laser induced ablation spectroscopy of droplets. An aerosol jet comprising a carrier gas and liquid phase sample droplets, less than about 10 microns in diameter, is formed. An emissive plasma plume is generated from the sample droplets using a pulsed laser to deposit energy at a focal point in the aerosol jet. Light from the plasma plume is gathered with a concave mirror and focused into one end of a fiber optic lightguide. The lightguide can transmit spectral emissions from the plume to a spectrometer/detector which can send wavelength and intensity values to a computer. The computer is operable to determine a liquid sample composition based on the wavelength and intensity values.

The first spectrometer can be relatively wideband to analyze a relative wide spectral segment and the other spectrometer can be high dispersion to measure minor concentrations. The apparatus can further comprise an unbranched lightguide fiber bundle to provide more light to a low sensitivity spectrometer. The apparatus can include an inductively coupled plasma mass spectrometer ICP-MS and a computer instructions operable to provide normalized LIBS/ICP-MS composition analyses.

Abstract: A method and apparatus for analyzing one or more elements of targeted moving snack food surfaces uses laser-induced breakdown spectroscopy to detect the presence, absence, or amount of an element on a heterogeneous surface, including seasoned and ready-to-eat snack foods. A laser is used to quantify the element concentration without destroying the targeted sample. An automated on-line system may be integrated into the method to create a closed-loop feedback control system, adjusting the concentration as desired.
