WebHydrolysed samples (amino acids) are derivatized for sensitive detection,separated by HPLC. Post-column derivatization was typical; however, pre-column derivatization has gained importance and can be achieved by a broader range of derivatization reagents. The use of internal and external standards is crucial. Column choice is a critical factor ...

Generally, a specific functional group of the compound participates in the derivatization reaction and transforms the … See more Several characteristics are desirable for a derivatization reaction: 1. The reaction is reliable and proceeds to completion. Less unreacted starting material will simplify analysis. Also, this allows a small … See more Chiral derivatizing agents react with enantiomers to give diastereomers. Since diastereomers have different physical properties, they … See more Classical qualitative organic analysis usually involves reacting an unknown sample with various reagents; a positive test usually involves a change in appearance — … See more Polar N-H and O-H groups on which give hydrogen bonding may be converted to relatively nonpolar groups on a relatively nonvolatile compound. The resultant product may be less polar, thus more volatile, allowing analysis by gas chromatography. … See more high waisted ankle jeans
