Improved H2S (Hydrogen Sulfide) Gas Analyzer Provides 1 ppbv Sensitivity
SUNNYVALE, Calif., June 3 /PRNewswire/ -- Picarro, Inc. has introduced a new and improved analyzer for monitoring trace levels of H2S (hydrogen sulfide) in ambient air, with a lower detection limit of 1 ppbv that is an order of magnitude lower than earlier models. Based on the company's WS-CRDS (Wavelength-Scanned Cavity Ring Down Spectroscopy) technology, the new Picarro G1104 H2S analyzer provides a very large dynamic range (up to 300 ppmv), operates in real time (seconds), and has no requirement for frequent calibration. Unlike H2S sensors based on competitive techniques, the G1104 H2S analyzer does not suffer from cross-talk due to changes in other ambient gas components, including other trace sulfur compounds such as SO2 and COS, as well as variations in moisture and CO2 at atmospheric levels. WS-CRDS is an ultrasensitive technology that measures the optical decay time in a flow cell using an internal laser beam with an effective path length of many kilometers. This enables the concentration of a particular species to be measured with sensitivity and precision several orders of magnitude higher than by any other optical technique. This new H2S analyzer achieves its superior precision and accuracy because it incorporates improved temperature control of the internal optical components. States Picarro President and CEO Michael Woelk, "This improved H2S performance is testament to Picarro's commitment to continued engineering to make better products that meet the changing and more demanding regulatory requirements for ambient gas analysis." The new Picarro G1104 H2S analyzer is compact and rugged with no moving parts, making it ideal for use in a wide range of sensing applications, operating equally well as a remote unattended monitor or as a state-of-the-art laboratory instrument. Specific applications include petrochemical plant emissions, in stacks, flares and flues, as well as emissions from landfills, sewage treatment plants and wastewater facilities. Picarro, Inc. is a privately held company dedicated to developing instrumentation for the highest sensitivity, precision and accuracy measurements of specific molecules of interest in environmental analyses, process monitoring, and emissions control. The company is a leader in wavelength scanned cavity ring down spectroscopy (WS-CRDS) technology with eight exclusive licenses to Stanford University patents and nine of its own on WS-CRDS extensions.
