Formaldehyde online monitoring device

Product Introduction

Formaldehyde (HCHO) is one of the most abundant components in atmospheric carbonyl compounds, and is a photochemical intermediate of volatile organic compounds (VOCs) and a major precursor of atmospheric reactive free radicals. It can affect the generation of ozone through photodecomposition and the formation of secondary organic aerosols by increasing surface active organic matter, playing an important role in atmospheric photochemical reactions.

HCHO-300Formaldehyde online monitoring deviceUsing acetylacetone fluorescence method, a fluorescent substance is generated based on the liquid-phase reaction of formaldehyde with acetylacetone and ammonia. The fluorescence signal is continuously measured by a photomultiplier tube to achieve real-time measurement. Can meet the online monitoring of gaseous formaldehyde samples and liquid formaldehyde samples.
