Sampling of Carbonyls - A Sampling Media Perspective
Formaldehyde, acetaldehyde, glutaraldehyde and acetone are the most commonly sampled carbonyls. These compounds are collected onto sampling media treated with 2,4-dinitrophenylhydrazine (DNPH) that derivatize the carbonyls to the more stable hydrazone derivatives. The derivatives are then measured by reversed-phase HPLC combined with UV detection. There are several analytical methods available to ...
