(44), alkalization and slow derivatization of samples with IAA and FDNB are performed before sample injection.
This is important, in particular, when HPLC methods with FDNB derivatization are applied because FDNB reacts with amino groups with a reaction time of some hours at alkaline pH.

After preliminary trials with various reagents, we chose FDNB derivatization for the gentamicin derivatization.
(14) reported derivatization of gentamicins with FDNB, but only [C.sub.1a] was separated from the two other components.
To our knowledge, this is the first time that FDNB was used for derivatization of amines in a SPE cartridge.
