Automated Online Desorption and Analysis of DNPH Derivatives of Formaldehyde, Acetaldehyde and Related Carbonyl Compounds Using a New Robotic Autosampler:

The analysis of airborne aldehydes and ketones first involves collection of the analytes by passing air through a cartridge containing 2,4-dinitrophenylhydrazine (DNPH).

As the air passes through the cartridge, the analytes react with the DNPH to form hydrazones which are immobilised on the cartridge.
