Analysis of Gas-Phase Formaldehyde by GC-FID Method Utilizing DNPH Derivatization

Formaldehyde is considered to be a harmful air pollutant and is subject to various regulations. Based on those regulations, analysis of ultra-trace amounts of formaldehyde is conducted by the HPLC, GC-FTD or GCMS methods after DNPH derivatization treatment.
However, it is also possible to detect DNPH-derivatized formaldehyde by GC-FID, and although this is not an official method, formaldehyde analysis is also possible by this technique.
