Trace formaldehyde detection


Formaldehyde, or CH2O, is commonly used in producing resins for coatings and adhesives, automotive materials, as well as materials for the textile industry. In these applications, the formaldehyde is normally incorporated into the material through a chemical reaction, and hence loses its chemical identity. Formaldehyde is also a by-product of some chemical reactions.

Aqueous solutions of formaldehyde, also known as formalin, are used as disinfecting agent for biological tissues, in that it is effective in killing bacteria and fungi. This toxicity to bacteria applies to humans as well, prompting manufacturers to reduce residual formaldehyde to safe levels in manufactured products.

CPG has developed sensitive techniques to measure trace levels of formaldehyde in a variety of matrices. This approach allows manufacturers to determine whether their formaldehyde levels have been reduced below threshold levels.
