derivatization

A method was established to determine sulfonamides in eel muscle by post-column derivatization high performance liquid chromatography.

abstract: Objective To establish a method using HPLC with post-column derivatization for detecting tobramycin sulfate drops.

A method was developed for pre-column derivatization and gas chromatographic analysis of validamycin A residue in soil.

New techniques are used in the derivatization of non-volatile species for gas chromatography.

Sample derivatization of blood sample and urine sample before GCMS analysis was needed.

Meanwhile, the influence of derivatization condition on it was tested, such as the derivatization reagent, time and temperature.

This can make heavy atom derivatization in the presence of reducing agents, difficult and frustrating.
