MOUNTAIN VIEW, Calif., Feb. 7, 2012 — Three new analyzers from Los Gatos Research (LGR) provide precision and accuracy for monitoring power plant emissions compliance with the Mercury and Air Toxics Standards (MATS) recently announced by the Environmental Protection Agency (EPA).
LGR’s EP series hydrogen chloride (HCl), hydrogen fluoride (HF) and combined HCl/HF analyzers allow both operators and regulators of fossil fuel power plants to measure these species with a precision of 0.1 ppb and an absolute accuracy of better than ±0.1 percent of recorded concentrations. They also deliver measurement concentrations up to 10 ppm.
Unlike other optical instruments, these new analyzers can deliver this performance in complex and varying gas streams, such as those encountered in power plant emissions.
The instruments are suitable for use in hostile industrial settings. Each one is self-contained, with an internal computer that can store data on its hard drive and send real-time data via digital or Ethernet outputs. The HCl and HF analyzers may be controlled remotely via the Internet using a web browser.
The gas analyzers are based on the company’s patented off-axis integrated cavity output spectroscopy (OA-ICOS) technology, a fourth-generation, cavity-enhanced laser absorption technique. This technique is more rugged and more precise than earlier cavity-enhanced techniques, such as conventional cavity ringdown spectroscopy (CRDS), because the performance of OA-ICOS does not need ultra-precise alignment or sub-nanometer stability of its optics, or a high degree of thermal control. This ensures higher absolute accuracy, longer maintenance intervals, higher reliability and reduced cost of ownership.
