The LI-COR Soil Gas Flux Systems provide a variety of ways to measure trace gas fluxes. Regardless of which method you use, chambers can make all the difference between dependable, reproducible data and questionable results. LI-COR chambers feature patented technology that maintains ambient pressure in the chamber during a measurement. The chambers also minimize disturbance to the soil around the chamber and ensure that sample air is well mixed inside the chamber.
Integrate an External Trace Gas Analyzer with the Smart Chamber Coming Soon
Integrate a trace gas analyzer of your choice with the Smart Chamber, providing the durability and patented performance of LI-COR soil flux chambers to your measurements.
Integrate an External Trace Gas Analyzer with the LI-8100A System
Combine the proven LI-8100A chambers and an external trace gas analyzer to create datasets that are easy to process with SoilFluxPro™ Software. In this configuration, you can take advantage of the sophisticated LI-8100A chambers and advanced data processing capabilities of SoilFluxPro Software to compute fluxes of trace gas species. This arrangement can be used in both single-chamber and multiplexed configurations.
Contact us to learn more about soil gas flux measurements that combine the LI-8100A with trace gas analyzers such as the LGR Ultraportable Greenhouse Gas Analyzer, Picarro G2508, or other analyzers.
Trace Gas Sampling Kit
The trace gas sampling kit is a simple add-on to the LI-8100A System, Smart Chamber, or Trace Gas Analyzer. It can be used with single chamber or multiplexed configurations to collect subsamples from the gas sampling tubes. By analyzing the gas concentrations of the subsamples, you can compute the flux rate of trace gas species using linear or exponential regression analysis.
The sampling kit also allows you to take advantage of the sophisticated 8200-01S Smart Chamber to measure fluxes of N2O, CH4, or isotopic species, without the need to install a laboratory gas analyzer in a field setting. The new Smart Chamber is self-powered and can log ancillary time stamps, GPS coordinates and soil moisture/temperature data as you sample the gases in the field, for lab analysis later.
Chamber Control Kit: Build Your Own Trace Gas Flux System with LI-8100A Chambers
If you're technically inclined and wish to develop your own datalogger, system controller, and data processing software, the chamber control kit provides all the hardware you need to control the LI-8100A Long-term chambers (8100-104/104C) with a Campbell® Scientific datalogger or Arduino electronics platform, while an external gas analyzer measures gas concentrations.
This arrangement combines the careful design of LI-8100A chambers and the trace gas analyzer measurements to create a versatile system for soil gas flux measurements. The chamber control kit (part number 8100-401) includes soil temperature and humidity sensors to provide data on soil conditions. In this configuration, you'll have to program the controller, log the data, and process the datasets.
