Instrument: LI-COR LI-840 NDIR Gas Analyzer
The LI-COR LI-840 is specifically designed for continuous monitoring of CO2 and H2O over a wide range of environmental conditions. The LI-840 is an absolute, non-dispersive, infrared (NDIR) gas analyzer based on a single, interchangeable optical path, and a dual wavelength infrared detection system.
Dissolved inorganic carbon (DIC) was measured on a non-dispersive infrared (NDIR) analyzer.
