Researchers in soil science are interested in rapid, accurate and reproducible greenhouse gas (GHG) flux monitoring methods in order to assess and compare various soil systems, either natural or farmed. Their works also serve as a basis for determination of best farming practices (in particular for fertilization) and future land management strategies. As they typically focus on carbon and nitrogen cycles, and on GHG emissions, researchers usually target CO2, CH4, N2O, and NH3.
Scientific teams are studying the emission rates of soil systems around the world, including in remote locations, and very often in rugged conditions. Beyond their need for high sensitivity with typical concentration levels barely higher than the ambient background, the quality of their results will strongly depend on high replication rate to account for the intrinsic heterogeneity of the soils. It means that they have to deal with large number of measurements, sometimes in experimental fields far away from analytical labs. Hence they need cost-effective direct measurement solutions which can be easily deployed in the field, and of course with superior specifications.
Our photoacoustic gas monitor INNOVA 1412i offers great value to the research teams with:
- High-end measurement specifications in the ppb-ppm range
- Rugged and reliable design
- Exceptional operational features for field deployment
It is an excellent instrument for multi-gas measurement with soil flux chambers. Its characteristics make it relevant either for static or dynamic chambers. Additional value is delivered by the INNOVA 1412i when paired with the Multipoint Sampler INNOVA 1409: they form a system capable of parallel multi-gas monitoring of several static chambers (up to 24) over long period of time.
Its low volume gas cell (only a few cc) is another definite advantage to pair it with bucket-size soil flux chambers.
Highly stable, “calibration-free” and not requiring any consumables, the INNOVA 1412i enables to scale up your soil science project with high replication rate at no cost.
Detection limits of typical gas of interest:
|Carbon dioxide||CO2||1.5 ppm|
|Nitrous oxide||N2O||0.03 ppm|
- Field deployable standalone monitor
- In-situ direct multi-gas monitoring
- Low volume gas sample cell
- Stable, Reliable, “zero” maintenance
- Scalability of measurement campaigns at high replication rate without extra cost (no carrier gas, no consumables)
It was already selected by multiple end-users worldwide who reported its use in a large variety of conditions over the planet: grasslands, wetlands, crop fields, rice paddies, etc.
