NETL: Compact Laser Spectroscopy for Downhole Applications
TECHNOLOGY SUMMARY
NETL has developed a new laser-induced breakdown spectroscopy (LIBS) design for that detects and measures of the concentration of elements. This device is ideal for a wide range of industrial applications and because of its innovative construction, can be produced at lower cost than the competition, while providing greater functionality.
Primary Application Area: Water, Waste, Environmental
Technology Development Status: Concept
TECHNOLOGY DESCRIPTION
NETL has developed a simplified design for laser-induced breakdown spectroscopy (LIBS) that allows the user to detect and measure the concentration of elements (metals and non-metals). This technology provides total internal reflection without the addition of external mirrors or coatings. This is due to its two-angled trapezoidal shape, which allows it to be folded, making it very compact. NETL’s new design is unique because it: minimizes optical components, minimizes optical analysis of light from the spark losses, and allows the laser to be out of the way while still performing and maintaining the lowest losses of return light. In addition to its uniqueness, this design is simplified because of its dove prism shape and high reflector and output coupler alignment, which doesn’t require any special attention during fabrication. The capabilities of this handheld device allow for a wide range of industrial applications, including oil/gas monitoring and water treatment because it is able to determine specific elements in liquid form onsite by using optical cables (as compared to performing a lab analysis). Finally, because of its innovative construction, this device can be produced at a lower cost than the competition, while providing more functionality.
