Contact LANL About This Technology

Technology Marketing SummaryScientists at Los Alamos National Laboratory (LANL) have developed an electrochemical carbon monoxide (CO) sensor that is more reliable and reproducible than any other CO sensor on the market today. The patented method for producing the sensor ensures reproducibility and reduces the need for calibration of every sensor coming off the production line.DescriptionInaccurate CO sensors on the market today result in alarms failing to go off, or alarms going off when CO is not present. Both can result in substantial costs to a company. LANL’s CO sensor offers a solution to this problem by providing a reliable CO sensor.Benefits

Electrodes for solid state gas sensor
A mixed potential electrochemical sensor for the detection of gases has a ceria-based electrolyte with a surface for exposing to the gases to be detected, and with a reference wire electrode and a sensing wire electrode extending through the surface and fixed within the electrolyte as the electrolyte is compressed and sintered. The electrochemical sensor is formed by placing a wire reference electrode and a wire sensing electrode in a die, where each electrode has a first compressed planar section and a second section depending from the first section with the second section of each electrode extending axially within the die. The die is filled with an oxide-electrolyte powder and the powder is pressed within the die with the wire electrodes. The wire-electrodes and the pressed oxide-electrolyte powder are sintered to form a ceramic electrolyte base with a reference wire electrode and a sensing wire electrode depending therefrom.
