I use DNPH, as a premade solution from Sigma Aldirch in phosphoric acid, but it seems like this along with the solid powder form of DNPH is being discontinued everywhere.
I use this for analysis of aldehydes with a UV-Vis detector. Seems like DNPH is being discontinued by nearly all suppliers.
Does anybody have an alternative HPLC suitable method for detection of aldehydes?
Thanks.
