Fast Determination of the Bitter and Clove-like Flavor in Beer with the Agilent 1290 Infinity II LC Abstract: The Agilent 1290 Infinity ll LC was used to determine the bitter compounds iso-alpha-acids andreduced iso-alpha-acids, and the clove-like phenolic flavor 4-vinylguaiacol in bottled beer. Asix-minute UHPLC method was developed to measure these important solutes in a single run. Diodearray and fluorescence detectors (DAD and FLD) were placed in-series for quantification ofiso-alpha-acids and reduced iso-alpha-acids, and of 4-vinylguaiacol, respectively. The fluorescencedetector provided aselective, sensitive, ancaccurate determination of ppb amountsCof4-vinylguaiacol. Some figures of merit are presented together with the profiles of a series ofdifferent beers. Agilent Technologies
