In air quality monitoring, accurate calibration of gas analysers or sensors is mandatory to ensure the reliability and precision of pollutant measurements. LNI Swissgas has been at the forefront of delivering advanced gas calibration systems tailored to meet the exacting demands of air pollution monitoring. Central to these systems is the innovative Sonic Nozzle technology, which guarantees high precision and consistent performance. With 0.5% vs 2% of uncertainty on the dilution Sonic nozzle are much more accurate than the mass flow controller.
The Importance of Accurate Calibration
Monitoring air quality involves detecting and measuring a range of pollutants, including ozone (O3), nitric oxide (NO), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and hydrocarbons (HC) at extremely low concentrations, often in the parts per billion (ppb) and parts per million (ppm) ranges. These measurements require highly sensitive analysers that must be regularly calibrated to maintain their accuracy over time. Regulations and device-specific requirements often mandate these calibration operations to ensure data integrity.
Challenges in Gas Calibration
Calibrating air quality monitoring systems presents several challenges:
LNI Swissgas addresses these challenges with its Sonimix calibrators, which utilise Sonic Nozzle technology for on-site generation of reference gases. This technology offers several key benefits:
