I am looking for a determination method of formaldehyde with HPLC or GC. I found in the literature a lot of methods but the most of the methods are using a derivation step. Can i measure fomaldehude without a derivation step?

Have you considered why you have not found any methods that do not require derivitization?
Perhaps a review of the nature of formaldehyde might be in order.

It is possible to detect formaldehyde without derivatization using electrochemical detection. One rather old reference is: Rocklin, R.D. "Ion chromatography with pulsed amperometric detection: Simultaneous determination of formic acid, formaldehyde, acetaldehyde, propionaldehyde and butyraldehyde." Adv. in Chem. 210, Ch. 2, p 13, Formaldehyde: Analytical Chemistry and Toxicology, V. Turoski, Ed. ACS, 1985.
