In recent years, mobile vehicle exhaust and industrial émissions of organic compounds VOCs are increasing, causing atmospheric photochemical smog pollution.
Formaldehyde is highly reactive in the atmosphère, and it can generate HO2 radicals through photolysis, and HO2 radicals react rapidly with NO to generate OH radicals, so formaldehyde becomes an important source of atmospheric OH radicals.
Low détection limit, with a détection limit of<50ppt.
Absorption module with 100% capture efficiency for accurate monitoring for formaldehyde concentration.
It can achieve high-precision temperature control of each module of the system (±0.1°C) to ensure the accuracy of the measurement results.
