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