| The double bond positions of 11 conjugated trienes were unambiguously located through a simple derivatization method amenable to nanogram-scale analyses. |
| The synthesis of dissymmetric, bidentate ligand precursors was attempted in a sequential derivatization of the diamine. |
| The comparison of the analytical results with and without derivatization shows that the sternutators in the investigated samples are partly metabolized. |
| The amino acids were separated in this HPLC-system by ion exchange and detected after post-column derivatization with ninhydrin at 570 nm. |
