Overview
The measurement accuracy is better than 0.1 ppb (with an average of 1 second and an acquisition speed of up to 20 Hz).
Product Details
In 2011,LGR(Currently under ABB Canada)Released its new version of nitrous oxide/carbon monoxide analyzer (N2O/CO-23r）Can simultaneously measure N in the ambient atmosphere2O. CO and H2O concentration, and record the dry and wet mole fractions without the need for sample drying. The analyzer is designed for various purposes, including trace gas monitoring, eddy related flux measurement, box method flux measurement, exhaust emission measurement, etc. The analyzer is particularly suitable for field measurements and has been successfully installed on NASA's DC-8 spacecraft for measuring the atmosphere in the troposphere and stratosphere. N2O/CO-23rAdopting built-in temperature control technology, it provides higher precision and accuracy, as well as smaller drift.
N2O/CO-23rThe off-axis integrated cavity output spectroscopy (OA-ICOS) technology designed with LGR patent (patent number: 6795190) eliminates the disadvantage of CRDS technology that requires continuous matching of optical cavity and laser wavelength during measurement to improve weak signal intensity. This eliminates the need for complex laser alignment adjustment, temperature control, and wavelength monitoring in the analyzer. Real time display of high-resolution laser absorption spectra. Adopting a built-in computer (Linux OS) to provide continuous storage and measurement of data. With remote control function, users can operate the analyzer from any location through the network, and can also share real-time data and perform instrument diagnosis through remote login.
