FMS-100 Formaldehyde Online Monitoring System

FMS-100 Formaldehyde Online Monitoring System

Product overview

In recent years, mobile vehicle exhaust and industrial emissions of organic compounds VOCs are increasing, causing atmospheric photochemical smog pollution. Formaldehyde is highly reactive in the atmosphere, 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.

The FMS-100 detects formaldehyde in air based on the fluorometric method and the Hantzsch reaction principle. The reaction is carried out quantitatively. In the presence of ammonia, formaldehyde reacts with acetylacetone to produce 3,5-diacetyl-1,4-dihydropyridine (DDL), which is excited by UV and the concentration of formaldehyde is determined by monitoring the fluorescence intensity with a photomultiplier tube.

Key features

• Low detection limit, with a detection 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.
• Autonomous adjustment of the instrument’s time resolution at the second/minute level.
• Visualization of formaldehyde concentration trends over time.
• The gas-liquid separation adopts the unique flow path design to ensure real-time measurement results.

Applications

• Formaldehyde concentration monitoring in ambient air.
• Atmospheric photochemical smog pollution warning system.
• Atmospheric environment complex pollution research.
