Portable N₂O/CO₂ Analyzer

Real-time Continuous Environmental and Source Monitoring:

The LI-G3006 N₂O/CO₂ Analyzer provides a powerful new monitoring tool for these two critical greenhouse gases (GHGs) in laboratory or field studies, offering sensitivity and accuracy previously only achievable with larger, more power-hungry instruments. Thanks to its extremely low power consumption, compact design, and lightweight construction, the LI-G3006 N₂O/CO₂ system supports field monitoring applications that were previously difficult to implement due to limitations of traditional analyzers. Furthermore, the system supports solar power, making it ideal for monitoring remote and unattended areas. Using absorption spectroscopy, the system exhibits excellent linearity over concentration ranges spanning several orders of magnitude, achieving ppt-level accuracy for N₂O and ppb-level accuracy for CO₂.

Key Features

• High Sensitivity: N₂O < 95 ppt/s, CO₂ < 200 ppb/s

• High Stability and Accuracy

• Supports sampling frequencies up to 5 Hz

• GPS Support: Generates spatial maps of N₂O and CO₂

• Supports the GPS fixed timestamp function

• Built-in Wi-Fi and RS232, with optional analog output

• Low Power Consumption: 27 W

• Maintenance-free sensor design

• The user can replace the filter element

Performance Notes:

• Typical time series from the LI-G3006 N₂O/CO₂ analyzer demonstrates stability of N₂O at 1s and 60s averages over several hours.

• The Allan deviation plot of N₂O shows the precision of 100 ppt and an average of 1 second.
