Designed for many demanding applications including eddy-correlation flux measurements, chamber flux measurements, combustion diagnostics, and trace-gas monitoring, these Analyzers have already been demonstrated successfully onboard NASA DC-8 aircraft for measurements in the upper troposphere/lower stratosphere. In fact, the CO Analyzer and the N2O Analyzer are ideal for measuring carbon monoxide and nitrous oxide, respectively, in ambient air with data rates of up to 20 Hz, less than 1% uncertainty, and better than 0.1% repeatability. Neither analyzer is affected by other atmospheric gases or changes in ambient atmospheric pressure.
Built using quantum-cascade lasers operating in the mid-IR, these instruments require cryogenic operation (using liquid-nitrogen cooling) of the laser and photodetector to provide state-of-the-art performance.
For applications requiring unattended long-term standalone operation, an included internal computer can store data practically indefinitely on its hard drive, and can send real-time data to a data logger through its analog, digital (RS232), and Ethernet outputs.
