Application of some modern sample preparation procedures for quantitative determination of vicinal diketones in beer

This work is focused on the evaluation and optimization of stir bar sorptive extraction as modern sample preparation procedure for the determination of vicinal diketones in beer. Validated parameters of this optimized method were compared with those of solid phase microextraction. The selective dete...

Zusammenfassung:	This work is focused on the evaluation and optimization of stir bar sorptive extraction as modern sample preparation procedure for the determination of vicinal diketones in beer. Validated parameters of this optimized method were compared with those of solid phase microextraction. The selective determination of diacetyl and pentandione was performed by gas capillary chromatography with electron capture detection.
