Oxygen Analyzers
In process and emission measurements, determining the oxygen content in a gas stream is a common application. We use three measurement techniques for oxygen detection: the electrochemical cell, the paramagnetic cell, and the zirconium dioxide cell. Depending on your specific application, we can recommend the most suitable measurement principle for your situation.
The Electrochemical Cell
Oxygen measurement and analysis using the electrochemical cell is typically applied in:
- Gas purity analysis;
- Inerting processes;
- Process gas analysis, and
- Ambient oxygen detection.
The Paramagnetic Cell
Oxygen measurement with a paramagnetic cell is commonly used in:
- Oxygen determination according to Pharmacopoeia standards;
- Inerting processes, and
- Emission measurements.
The Zirconium Dioxide Cell
Oxygen measurement with a zirconium cell is used in:
- Combustion processes;
- Emission monitoring, and
- Industrial furnaces.
Oxygen Measurement as Part of Multi-Gas Analysis
Oxygen analysis is often part of a broader gas analysis setup. Electrochemical and paramagnetic cells are commonly integrated into cold extractive gas analyzers. Zirconium cells are often found in inline probes or hot extractive analyzers, such as FTIR emission analyzers. Oxygen measurement is frequently included in multi-gas analyzer applications.
Paramagnetic Oxygen Analyzers
Measurement services and laboratories frequently use paramagnetic oxygen analyzers. These are highly accurate and offer a fast response time. This measurement principle is the reference method according to EN 14789 for verifying continuous oxygen monitors in emission measurement setups. For emission reporting, accurate and reliable oxygen measurement is essential for properly correcting and calculating the emission values of other components.
