Using LI-COR Soil Flux Chambers for Monitoring Trace Gases

Using LI-COR Soil Flux Chambers for Monitoring Trace Gases

LI-COR soil CO2 flux chambers (8100-104 Long-Term Chamber and 8100-104C Clear Long-Term Chamber) are designed to be left in the field for extended lengths of time to make unattended flux measurements. Originally designed to be used with the LI-8100A Automated Soil CO2 Flux System for monitoring soil CO2 flux, these chambers can also be operated independently using a simple Transistor-transistor logic (TTL) controller and a 12 VDC supply. Used independently, these chambers can be combined with trace gas…

Avoid ‘mass’ confusion with the LI-6400XT

Avoid ‘mass’ confusion with the LI-6400XT

Gas exchange from the surface of a leaf is typically reported in micromoles of CO2 exchanged per square meter of substrate per second, abbreviated as µmol m-2 s-1. However, users may want to express gas exchange rates on a mass basis, such as µmol kg-1 s-1. The LI-6400XT Portable Photosynthesis System can perform these calculations for you, while measurements are ongoing or after data are collected during post-processing.

To express gas exchange rates on a mass basis during the measurement,…
