Air Pollution Substance Measurement "Reagent for Aldehyde Measurement"

Handling of standard substances and internal standard materials used for the measurement of formaldehyde/aldehydes in the "Manual for Measurement Methods of Harmful Air Pollutants" by the Ministry of the Environment!

The "Standard Solution for Analyzing Aldehydes" is for measuring air pollutants. Several aldehydes are listed in regulations and guidelines related to chemical substances in indoor air pollution, specific odor substances under the Odor Prevention Law, and harmful air pollutants. The analysis of these aldehydes is conducted by collecting them using a 2,4-DNPH impregnated cartridge adsorbent and derivatizing them into aldehyde-DNPH compounds. The DNPH-derivatized compounds are then separated and analyzed using GC or LC equipment. We provide standard substances and internal standards used in the "Manual for Measuring Harmful Air Pollutants" (Revised March 2019) published by the Ministry of the Environment, specifically in Chapter 1 of Part 4, "Measurement Methods for Formaldehyde and Acetaldehyde in the Atmosphere."
