What Is Zero Air and Why Is It Important?
Zero air is atmospheric air that has been purified to remove contaminants such as:
- Total hydrocarbons (THC)
- Carbon monoxide (CO)
- Nitrogen oxides (NOx)
- Sulfur dioxide (SO₂)
- Carbon dioxide (CO₂)
- Moisture and particulates
This ultra-clean air is crucial in preventing background interference during measurements.
Zero air is critical for:
- Zero checks and calibration of gas analyzers (NOx, SO₂, CO, O₃, VOC)
- Carrier and dilution air in calibration systems
- Combustion air for FID analyzers
- Accurate operation of the Zero Air Generator for TOC analyzers
Without a reliable Zero Air Gas Generator, analytical results may drift, resulting in inaccurate data and potential regulatory non-compliance.
Zero Air Generator for TOC Analyzers
A Zero Air Generator for TOC applications plays a vital role in ensuring precise carbon measurement. TOC analyzers rely on contaminant-free air to avoid background carbon interference.
Benefits of TOC applications:
- Eliminates hydrocarbon background noise
- Ensures stable baseline measurements
- Improves repeatability and accuracy
- Reduces dependency on gas cylinders
For laboratories handling environmental water testing, pharmaceuticals, or industrial effluent analysis, a Zero Air Generator is a long-term, cost-effective solution.
Why Choose an On-Site Zero Air Gas Generator?
Traditionally, laboratories and monitoring stations depended on high-pressure zero air cylinders. However, modern Zero Air Gas Generators offer clear advantages:
✔ Consistent Purity
- THC levels as low as <0.05 ppm
- Effective removal of NOx, SO₂, moisture, and particulates
✔ Cost Efficiency
- No recurring cylinder rental or refilling costs
- Payback typically within 12–18 months
✔ Improved Safety
- Eliminates risks of handling high-pressure cylinders
✔ Environmentally Friendly
- Reduced transportation emissions
- Lower carbon footprint
Advanced Zero Air Generators for Air Pollution Monitoring
For Air Pollution Monitoring (APM) networks, calibration accuracy is non-negotiable. High-performance zero air generators, such as the SONIMIX series by LNI Swissgas, are widely used across global AQM networks.
Popular configurations include:
- Portable Zero Air Generators for mobile labs and field calibration
- Rack-mounted Zero Air Gas Generators for fixed monitoring stations
- Integrated oil-free compressors for continuous operation
These systems are engineered for seamless integration with gas dilution calibrators, ensuring compliance with EN and international monitoring standards.
Key Applications of Zero Air Gas Generators
- Air Quality Monitoring Stations (AQMS)
- Environmental Testing Laboratories
- TOC Analyzers
- Gas Calibration Systems
- Research & Development Labs
