AMI Deltacon Degasser – Accurate Conductivity Measurement with CO₂ Removal
In power plants and steam generation systems, dissolved carbon dioxide can influence conductivity measurements and make it difficult to detect ionic contamination accurately.
The SWAN AMI Deltacon Degasser removes dissolved CO₂ from the sample before conductivity measurement. This allows operators to measure true ionic conductivity, improving the detection of impurities that may cause corrosion or operational problems in the steam-water cycle.
By eliminating the influence of carbonic acid, the system provides more reliable water chemistry monitoring in critical power plant applications.

Degassing technology improves conductivity measurement accuracy
In many steam-water systems, carbon dioxide dissolves in the sample and forms carbonic acid, which increases conductivity without indicating harmful contamination.
The AMI Deltacon Degasser removes dissolved CO₂ through a membrane-based degassing process before the sample reaches the conductivity sensor.
The process typically includes:
- Sample conditioning and controlled flow
- Membrane degassing to remove dissolved CO₂
- Conductivity measurement after degassing
This ensures that the conductivity measurement reflects true ionic contamination rather than dissolved carbon dioxide.
Part of a Steam & Water Analysis System (SWAS)
