Formaldehyde is used in the production of dyes, medicines and in textile finishing. It is a strong reducing agent and is carcinogenic, mutagenic and toxic to reproduction. When determining it, a distinction is made between the formaldehyde released by emissions, the formaldehyde content and free formaldehyde. With the first two methods, other aldehydes including glutaraldehyde and ketones can also be determined quantitatively. In the third procedure, the "free formaldehyde" is determined. The sample is heated in an inert, dry atmosphere and the released formaldehyde is collected in a gas cartridge.
