Configuration examples - flasks and other chambers
In addition to the soil and canopy chambers described previously, the LI-8250 is supports flasks and other chambers. The following illustrations display some configurations.
Flask CO₂ system
Any of the previous configurations can measure gas exchange from samples in flasks. With this setup, you'll use the flask sampling kit instead of soil chambers.

Flask and soil CH₄/N₂O/CO₂ isotope system with 8250-02 Cal. Manifold and 8250-01 Ext. Manifold
Flask and chambers can be combined in a single system. The calibration manifold controls flow from a tank of zero gas. This configuration can be expanded with 8250-01 Extension Manifolds, flasks, and chambers. The LI-870 is not supported in this configuration.
