The Picarro G5310 gas concentration analyzer is a highly precise instrument designed for measuring the concentrations of nitrous oxide (N2O), carbon monoxide (CO), and water vapor (H2O) in the atmosphere. It utilizes mid-infrared cavity ring-down spectroscopy (CRDS) technology, which allows for simultaneous and continuous measurement of N2O and CO concentrations.
This analyzer is specifically tailored for atmospheric science, air quality monitoring, and emissions quantification. It meets the performance requirements set by the World Meteorological Organization (WMO) and the Integrated Carbon Observation System (ICOS) for N2O and CO atmospheric monitoring.
The key features of the Picarro G5310 gas concentration analyzer include:
- Simultaneous and Continuous Measurement: The instrument provides simultaneous measurement of N2O and CO concentrations, allowing for real-time monitoring of both gases.
- Mid-IR CRDS Technology: The analyzer utilizes mid-infrared cavity ring-down spectroscopy, a highly sensitive and precise analytical technique that enables accurate measurement of gas concentrations at parts-per-trillion (ppt) levels.
- Compliance with WMO and ICOS Requirements: The instrument meets the international ambient atmospheric monitoring requirements established by the WMO and ICOS for N2O and CO measurements.
- Water Correction: The analyzer’s software automatically corrects for the presence of water vapor in the sampled air and reports the dry gas mole fractions. This feature helps reduce research complexity and consumable costs associated with water vapor interference.
- Precision and Drift: The precision of the instrument is reported as <200 ppt and <40 ppt for N2O and CO, respectively, at 5 seconds and 5 minutes measurement intervals. The drift, defined as changes in measurement values over time, is reported as <100 ppt for N2O and CO over 24 hours at standard temperature and pressure (STP).
Overall, the Picarro G5310 gas concentration analyzer is a highly accurate and reliable instrument for simultaneous measurement of N2O, CO, and water vapor concentrations in the atmosphere. It is designed to meet the stringent requirements of atmospheric science research, air quality monitoring, and emissions quantification applications.
