Description

Analysis Note Following pre-column derivatization of primary amino groups using o-phthaldialdehyde/thiol reagent, the Ascentis RP-Amide was used for the analysis of biogenic amines commonly found in wines. These include histamine, spermine, spermidine, tyramine, putrescine and cadaverine. Structures along with an optimized chromatogram are presented.
