of them need time-consuming sample pretreatment. Conversely, methods are missing for a rapid screening of non-pre-treated
samples, with useful application in the agri-food industry, from process control to fraud. Selected ion recording mass mode after
liquid chromatographic separation was used for the detection and quantification of free polyphenols in three craft beers, after just
