Environmental monitoring for environmental protection – precise calibration gases for reliable air analysis
Environmental monitoring for environmental protection is a key tool for assessing air quality and ensuring compliance with legal emission limits. Across Europe, environmental authorities operate a dense network of measuring stations for the continuous monitoring of airborne pollutants. Among other things, the following are recorded:
- Carbon monoxide (CO)
- Carbon dioxide (CO₂)
- Nitrogen oxides (NOx)
- Sulfur dioxide (SO₂)
- Hydrocarbons
Detection is carried out using both continuous measurement methods such as infrared and UV spectroscopy and gas chromatographic analyses. These systems must be regularly calibrated with high-precision calibration gases for environmental monitoring to ensure measurement accuracy, especially in the trace range.
Traceline mixtures – calibration gases for trace gas analysis
Messer offers special Traceline mixtures for applications in environmental analysis with very low concentration levels. These high-precision calibration gases enable reliable calibration and quality assurance of analytical instruments that measure trace gases in the ppm to ppb range. Depending on the application, Traceline mixtures can be supplied with a certified analysis certificate in accordance with EN ISO/IEC 17025.
Typical characteristics of Traceline mixtures:
- Concentrations: 1 ppm to 1 ppb
- Components: NO, NO₂, SO₂, CO, CO₂, ...
- Carrier media: synthetic air or high-purity nitrogen
- Certified traceability to national and international reference standards
- Stability period: up to 24 months, depending on matrix and component
These calibration gases are essential for measurement programs in accordance with EU Air Quality Directive 2008/50/EC, EN 14211 (NO/NO₂), EN 14662 (VOC), and other industry-specific standards.
