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
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.
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.
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
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.
