LI-COR Soil Flux System

Collect survey, long-term, and multiplexed measurements and evaluate the temporal and spatial variation of your fluxes with confidence. The LI-8100A Analyzer Control Unit and LI-8150 Multiplexer provide durable and consistent performance while the unique design of LI-COR chambers is optimized for reducing the interference of the chamber with natural soil activity, allowing for the interaction of gases, water, and sunlight with the soil inside the collar.

LI-8100A Analyzer Control Unit

LI-8100A Analyzer Control Unit

The LI-8100A is a portable, automated system that enables you to simply and reliably conduct survey and long-term measurements over a study site using the 10cm or 20cm survey chambers or clear or opaque long-term chambers. The LI-8100A with a long-term chamber is ideal for assessing the temporal variability of CO2 flux at a study site. The analyzer control unit contains an infrared gas analyzer and a connection panel to interface with long-term chambers, additional gas analyzers, and the LI-8150 multiplexer.

+ Why Choose the LI-8100A?

Long-Term Chambers

Whether you choose a single chamber or multiplexed long-term configuration, the chambers can make all the difference between dependable, reproducible data and questionable results. LI-COR chambers are designed with a perforated base and patented pressure vent to preserve the integrity of your measurement.

Long term chamber 8100-104

Opaque Long-Term Chamber

The opaque long-term chamber (8100-104) is finished in durable, highly reflective white enamel. Rotating away from the soil collar, the motorized chamber allows for autonomous measurements in the field over long periods of time minimizing disturbance to the soil surface inside the collar.

Clear long term chamber 8100-104C

Clear Long-Term Chamber

The clear chamber (8100-104C) is designed for long-term net carbon exchange measurements. It features a durable, clear chamber top so that plants are exposed to sunlight during measurements.

LI-8150 Multiplexer

The LI-8150 Multiplexer provides the ability to measure the gas exchange from multiple long-term chambers, providing a large sample size that allows you to determine spatial and temporal flux rates with confidence. Capable of running autonomously for months, the LI-8150 system collects a continuous dataset from up to 16 chambers to characterize spatial and temporal variation in gas exchange over a research area. By integrating additional gas analyzers like the LI-7810 CH4/CO2/H2O Trace Gas Analyzer, long-term and multiplexed systems also support methane fluxes while third-party gas analyzer integration provides support for fluxes of isotopologues and other gases.

LI-8150 Multiplexer

Integrate New LI-COR Trace Gas Analyzers with Your LI-8100A Multiplexed System

Expand your measurement capabilities to new gases: LI-8100A systems are now compatible with new laser-based trace gas analyzers from LI-COR, including the LI-7810 CH4/CO2/H2O analyzer.

    Why integrate a LI-COR Trace Gas Analyzer into Your System?

  • No need for elaborate field structures: low power requirements and weather-resistant case mean a simple cover or stand, and solar or other AC power supply are all that is required for deployment.
  • Exceptionally precise and stable CH4 measurements (with the LI-7810 CH4/CO2/H2O analyzer).
  • Highly stable optical bench means user calibration is required infrequently.
