Customizations and other applications

This section describes ways to use the LI-8100A that are beyond the basic soil gas flux capabilities. For some applications, we direct you to supplementary documents on the procedure.

Trace gas flux measurements

For gases such as NO2, N2O, CH4, or isotopologues, you can add a trace gas analyzer to the LI-8100A system, log the data in the LI-8100A, and process the data in SoilFluxPro™ software. Download the application note called "Capturing and Processing Soil GHG Fluxes Using the LI-8100A" from the LI-COR support site: and select the LI-8100A.

Flask measurements

You can configure the LI-8100A and LI-8150 multiplexer to measure gas exchange from discrete samples such as soil samples, fruit, or small animals in flasks or custom chambers. This is described in detail in an application note called "Measurement of CO2 Evolution in a Multiplexed Flask System."

Profile measurements

You can configure the system to measure concentrations across a vertical or horizontal profile. This is described in the document called "Atmospheric CO2 Profile Measurements Using the LI-8100A/LI-8150 System."

Trace gas sampling kit

The trace gas sampling kit (part number 8100-664) is used to collect air samples from the same air stream used by the LI-8100A Automated Soil CO2 Flux System. The collected sample can be analyzed to measure trace gases such as methane (CH4), ammonia (NH3), nitrous oxide (N2O), isotopologues.

Chamber control kit

The chamber control kit (part number 8100-401) enables you to use a long-term chamber with a home-made controller and third-party gas analyzer.
