The EGA61 Multi-Sample CO2/H2O Analyser is a versatile, high-precision laboratory instrument designed to analyse CO2 and water vapour evolution for up to 25 samples.
Widely employed in studies such as microbial degradation of leather, humus decomposition under alpine conditions, and agrochemical impacts on soil microbial activity, the EGA61 delivers robust, accurate, and consistent data to support diverse environmental and ecological research.
How the instrument works
The EGA61 automatically and sequentially samples gas from up to 25 connected sample chambers, each managed by its own dedicated pump.
Gas from each channel is drawn at a precisely controlled flow rate through an infrared gas analyser (IRGA) and a humidity sensor. CO2 and H2O concentrations are measured, and results are logged to an SD card or transmitted to a connected PC.
The instrument employs a zero calibration channel with soda lime to generate a CO2‑free reference, ensuring accurate baseline corrections.
Applications
- Soil respiration studies and carbon cycling
- Assessment of agrochemical effects on microbial activity
- Studies on microbial degradation of various substrates
- Climate change and environmental monitoring
- Laboratory-based soil and substrate gas exchange experiments
Key features
