The product complies with GB/T 15516-1995 Determination of Formaldehyde in Air Quality - Acetylacetone Spectrophotometric Method.
Application Scope
The instrument is applied in ambient air monitoring areas such as air stations, residential areas, tourist attractions, industrial parks, etc.
System Introduction
After formaldehyde gas is absorbed by water, it reacts with acetylacetone in acetic acid-ammonium acetate buffer solution at pH=6 under boiling water bath conditions to rapidly form a stable yellow compound. The absorbance is measured at 413nm wavelength, and the formaldehyde content in the air is proportional to the absorbance.
