In 2021, to achieve the goal of carbon peaking by 2030 and carbon neutrality by 2060, the Ministry of Ecology and Environment has issued the Guidance on Coordinating and Strengthening the Work Related to Climate Change Response and Ecological Environmental Protection and the Carbon Monitoring and Assessment Pilot Work Program. Proposing to strengthen greenhouse gas detection and implement reduction pollution and carbon, thus further optimizing the energy mix and driving industries to improve efficiency and reduce consumption. As a global technology leader, FPI has been committed to researching and developing high-end analyzers and instruments and embedded them throughout the lifecycle of the products and solutions we provide to customers.

AQMS-450 CO₂ Analyzer

The AQMS-450 is an FPI independently developed ozone analyzer based on chemiluminescence technology, used to detect and evaluate the CO₂ concentration level of one of the environmental air quality parameters (SO₂, NO₂, CO, O₃, PM2.5, and PM10). This analyzer can measure the concentration of CO₂ in μmol/mol (ppm) level, with strong anti-interference capability, high repeatability, and accuracy. Meantime, its measuring data and condition information such as default, temperature, flow, pressure will be automatically transmitted and inquired. It is convenient and accurate for competent departments to estimate the air quality.

Principle:

The analyzer adopts GFC NDIR technology. The two beams passing through the GFC enter the White cavity, and the intensity of the beam passing through the reference chamber is not affected by the CO₂ in the cavity and is measured as the reference signal ruler. The intensity of the beam passing through the measurement chamber is attenuated by the absorption of CO₂ radiation in the chamber and is measured as the measurement signal M. According to Lambert's law, the CO₂ concentration in the gas to be measured is obtained by comparing the ratio of the two signals.

Features：

High responsiveness, high repeatability and easy operation.

Range up to 2000ppm, with a wide measurement range and low detection limit.

Integrated CO₂ purge device to eliminate the interference of ambient CO₂ concentration fluctuation on the instrument measurement.

Adopt the White cavity design. The surface of optical devices uses special anti-corrosion treatment technology, good stability, long service life.

Application:

Environmental monitoring in urban areas, carbon emission monitoring in industries campus boundaries, routine CEMS emission monitoring.
