The article describes methods used for testing formaldehyde and other aldehydes or ketones. Methods using dinitrophenylhydrazine (DNPH) derivatization followed by liquid chromatography (LC) have been published by the U.S. Environmental Protection Agency (EPA). An example of LC chromatogram which shows the analysis of common aldehydes and ketones using DNPH derivatives is presented. Meanwhile, EPA Method 556 uses pentafluorobenzyl hydroxylamine to form oxime derivatives of the aldehydes.
