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?

with regards Johan Hoesen

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.
