Formaldehyde Testing for IAQ Applications - Application Note

Formaldehyde (HCHO) is a colorless, reactive and pungent smelling gas. Formaldehyde is one of many compounds known as volatile organic compounds (VOCs). While it is possible to quantify the total volatile organic compounds (TVOCs) present, formaldehyde is usually of heightened interest by itself due to its significant health concerns, even at extremely low concentrations. Formaldehyde is used widely by industry in various building materials and household products.
