Portable FTIR elevates short-term emission campaigns: Airmes AG & GT6000 Mobilis
Process understanding and optimization demand more than manual snapshots. Airmes AG, a Swiss company specializing in air quality and regulated emission measurement, selected the GT6000 Mobilis portable FTIR system to complement reference methods during short‑term compliance campaigns. By capturing continuous temporal profiles for key gases, and with certified performance under EN 15267‑4 (MCERTS QAL1), the team gains a more complete view of emissions between and during manual sampling points.
Why Airmes AG needed more than manual methods
Manual reference methods recommended by the Swiss Federal Office for the Environment (FOEN / Bundesamt für Umwelt, BAFU) for substances as SO2, HCl, HF and NH3 are indispensable for regulated monitoring, but they provide snapshots rather than time‑resolved behavior.
Although these snapshots are sufficient for evaluating plants with relatively constant emissions, more complex issues require a precise and time-resolved analysis of the exhaust gas composition.
To measure how concentrations change over time, Airmes AG sought a portable, multi‑gas approach that could run in parallel with reference methods, revealing the temporal progression of regulated gases and selected volatile organic compounds (VOCs) to improve process understanding.
Continuous FTIR profiles helps us to identify what happens between and during manual reference measurements, thereby providing clarity in understanding and optimizing processes.” Dr. Joachim Elsig, Managing Director, Airmes AG
How GT6000 Mobilis delivers continuous multi‑gas insight
Airmes AG deployed GT6000 Mobilis + PSS Plus, forming a complete field-ready Portable Automated Monitoring System (P‑AMS):
- FTIR analyzer (GT6000 Mobilis) for simultaneous multi‑gas measurement and immediate on‑site results and deeper analysis with Calcmet software (Easy/Expert).
- Heated sampling system (PSS Plus) designed for hot, wet, corrosive streams, with integrated O₂ sensor for complete campaigns.
- Local training and service supported by Gasmet Technologies teams, to ensure smooth field operation and responsive assistance.
This portable setup enables continuous profiles for critical components and the flexibility to identify and quantify individual organics when the exhaust‑gas composition is either known or can be narrowed down.
With GT6000 Mobilis, Airmes AG now supplements manual reference measurements with continuous data, and can display the progression of the measured concentrations in a time-resolved manner.
Results: continuous profiles that enrich reference measurements
Working alongside reference methods, GT6000 Mobilis allows Airmes AG to continuously record gases at the stack typically captured discontinuously, including H₂O, SO₂, HCl, HF, NH₃.
The time‑resolved data exposes transient spikes and process drifts, and when applicable, supports component‑level VOC insight beyond total carbon, enabling comparison with the Swiss Air Pollution Control Ordinance (Annex 1) after correction to the reference method.
Why GT6000 Mobilis (FTIR P‑AMS): efficiency and audit readiness
Beyond the measurement advantages, the portable FTIR approach drives campaign efficiency in very concrete ways. Because the analyzer produces immediate, high‑quality results on‑site, teams avoid extra revisits purely to “re‑sample,” keeping short‑term campaigns tight and focused rather than fragmented across multiple tools and appointments.
Also, the solution is audit‑ready by design.
Certified ranges, traceable software logs, and stable continuous datasets create a clear evidence trail for regulators. Instead of piecing together discrete results, campaigns deliver cohesive, time‑resolved data that supports compliance documentation without adding administrative overhead.
QAL1-Certified performance
GT6000 Mobilis is EN 15267‑4 (MCERTS) QAL1‑certified and TÜV Rheinland approved for periodic emissions monitoring as a portable system (P‑AMS). The certified measuring ranges cover eleven gaseous components: CO, NO, NO₂, N₂O, HCl, NH₃, CO₂, H₂O, CH₄, H₂CO, and O₂ (via the zirconia sensor in PSS Plus).
Beyond the certified list, FTIR can accurately measure hundreds of additional compounds using Gasmet libraries, including SO₂ and HF, supporting research, troubleshooting, and compliance‑adjacent use cases. For nitrogen oxides, NOx can be reported as the sum of NO and NO₂ in line with the certificate.
