Suitable quantification standards were generated by derivatized with labelled 13C2-dansyl chloride and 13C2dansylhydrazine. The derivatization of the standards and the urine sample was performed using ...

Analysis of the herbicide, its metabolites and similar compounds is difficult due to the lack of retention by reverse phase techniques. Alternatives include derivatization and ion chromatography.

Ion-exchange chromatography post-column derivatization is used to determine ultra-low levels of nitrite in three excipients. The 2018 discovery of the probable and possible human carcinogen ...
