Laser analyzer is highly selective and interference-free
ABB Measurement & Analytics
The LGR-ICOS Model 950 (photo) is an online, continuous laser-based process analyzer that performs ultra-sensitive measurements of industrial trace gases, in applications including calibration, management of industrial gas blankets, tank and pipeline operations and more. It uses patented Off-Axis integrated cavity output spectroscopy (OA-ICOS) technology — a cavity-enhancement absorption technique that extends optical path lengths by multiple miles to greatly improve the sensitivity to such trace gases as CH 4, CO 2, CO, O 2, H 2 S, HCl, NH 3, HF, C 2 H 2, and others, says the company. The device is said to be easy to use, it requires no field calibration, and has minimal preventive maintenance requirements, and continuous diagnostics and warnings help to avoid emergency repairs. — ABB Measurement & Analytics, San Jose, Calif.
