In-situ or extractive? The decision for the right gas analysis method significantly determines plant safety and ongoing operating costs. While in-situ measurements score with extremely fast data directly in the process, extractive analytics excel with aggressive gases, complex multi-gas analyses, and noticeable savings through the use of multiple measuring points. Find out in this article which method sustainably reduces your process costs.

Greenhouse Gas Monitoring at Clarification Basins – the Fresenius Off-Gas System
Invisible Climate Killers in Focus: How Wastewater Treatment Plants Must Now Respond
They are indispensable for clean water, but are secretly among the largest sources of direct greenhouse gases: Modern wastewater treatment plants emit massive amounts of highly climate-damaging nitrous oxide and methane. With the new EU Wastewater Directive, comprehensive monitoring of these emissions is now mandatory. The Fresenius Off-Gas System offers operators a turnkey complete solution that determines exact emission rates directly at the basin – without cloud dependency, completely autonomous, and with 100% data sovereignty.
Mobile Biogas Spot Measurement: GAP100 in Field Operation
Biogas plants are sensitive powerhouses: if the biological balance in the fermenter is not right, efficiency losses and expensive damage to costly combined heat and power plants are imminent. Those who want to optimally monitor eleven different measuring points often face the choice between unaffordable stationary technology and inaccurate compromises. Our practical report shows how mobile spot measurements ensure maximum process reliability even at frosty temperatures and with aggressive gases like hydrogen sulfide – and why a clever deployment concept makes all the difference.
ECS vs. NDUV: The optimal technology for H2S analysis in biogas plants
Hydrogen sulfide is the enemy of every plant—but how can you tackle it most efficiently? Between cost-effective routine and state-of-the-art NDUV precision lies the future of your process optimization. A look behind the membranes and light guides shows: choosing the sensor is more than just a cost issue—it is the safety update for your entire plant.
Gas analysis in the cloud with the Cloud Connect Kit
Gas analysis systems generate valuable measurement data – but they often remain difficult to access.
The Cloud Connect Kit finally makes monitoring easy: real-time data, transparency in operation, and digital connection without IT effort.
Plug in. Connect. Keep track.
Read Now: How We Compensate for Cross-Sensitivities in our Measurement Technology
What if your measurement technology could detect and correct interferences on its own? Our intelligent cross-sensitivity compensation makes exactly that possible. It uses targeted wavelength analysis and mathematical correction methods to precisely separate superimposed signals.
The result: accurate, stable measurement values – even where other systems reach their limits. Discover in the white paper how Fresenius Umwelttechnik elevates gas analysis to a new level with this.
