Measurement of Volatile Aldehydes in Beer by Solid-Phase Microextraction-Gas Chromatography/Mass Spectrometry

摘要

1. Standard deviations for the measurement of seven compounds in packaged American lager beer by solid-phase microextraction-gas chromatography/mass spectrometry (SPME GC/MS) were determined. With limited results, the standard deviations (SD) and percent relative standard deviations (%RSD) for the seven compounds studied for fresh beer sample pair C/D ranged from 0.0283 to 26.69 ug/L and 20.48 to 85.26%, respectively, and were judged unacceptable. 2. With limited results, the SD and %RSD for the seven compounds studied for aged beer sample pair A/B ranged from 0.0941 to 651.7 μg/L and 23.84 to 96.79%, respectively, and were judged unacceptable.
