Formaldehyde detection is the quantitative detection of formaldehyde in air, water, food, clothing, etc. using specific methods or instruments. So, what are the methods for formaldehyde detection?

Formaldehyde source

1. Various types of phenolic resin adhesive artificial boards used as decorative materials for wall panels, ceilings, etc., such as plywood, plywood, fiberboard, and particleboard,

2. Decorative materials that contain formaldehyde and may emit to the outside world, such as wall coverings, wallpaper, paint, and paint pipes;

3. Indoor displays and daily necessities that may emit formaldehyde, such as furniture, chemical fiber carpets and foamed plastics;

4. Some materials that emit formaldehyde after combustion, such as cigarettes and some organic materials.

5. Some fragrances and mosquito repellents also contain formaldehyde.

6. White or wrinkle free clothing, especially some jeans, clothes that claim to be 100% wrinkle and shrink resistant, or cotton wrinkle free shirts that are molded with formaldehyde resin, all contain formaldehyde. Formaldehyde has a strong irritant effect on human skin, causing eczema and systemic allergies.

7. Adding formaldehyde to food often plays a role in white and protein coagulation, as well as preservation and preservation.
