  • Mercury sensor for detecting, differentiating, and measuring organic and inorganic mercury compounds
    Patent number: 9791428
    Abstract: The invention relates to a sensor assembly to detect and quantify organic and/or inorganic mercury compounds, including elemental mercury that may be present in gases or liquids, such as natural gas, air, condensates, crude oil, refined petroleum gas or liquids, and water including connate water, condensed water and water containing hydrate inhibitor(s). The sensor assembly includes a housing having a flow channel defined by an inlet, a sensor array, and an outlet. The sensor array is based on the differential sorption properties measured using a surface acoustic wave (SAW) sensor array, a chemiresistor array, or a combination of the two.
