High-Efficiency CO Removal Catalyst for Ultra-Pure Zero Air Systems
What Is a CO Catalyst in a Zero Air Generator?
CO catalyst for zero air generators is a critical purification material designed to remove carbon monoxide (CO) from compressed air streams. In high-precision gas analysis systems, even trace levels of CO can compromise measurement accuracy.
Our Hopcalite-type CO oxidation catalyst (Mn–Cu based) enables efficient CO removal under ambient or low-temperature conditions, ensuring stable production of ultra-pure zero air.
Why CO Removal Is Critical in Zero Air Systems？
Zero air generators are widely used in:
- Ambient air monitoring systems
- Gas analyzers (O₃, NOx, SO₂)
- Laboratory calibration systems
- Semiconductor gas analysis
However, untreated air typically contains ppm-level CO, which can:
- Interfere with analyzer signals
- Cause baseline drift
- Reduce calibration accuracy
- Affect ozone measurement stability
Solution: A high-performance CO removal catalyst ensures CO levels are reduced to ppb or near-zero levels.
How the CO Removal Catalyst Works？
Our Hopcalite catalyst promotes the oxidation of carbon monoxide into carbon dioxide:
CO + 1/2 O₂ → CO₂
Key characteristics:
- Operates at room temperature or low temperature
- No external energy required
- Fast reaction kinetics
- Ideal for continuous flow systems
