Headspace Gas Chromatography-Flame Ionization Detector Analysis for Beer Volatiles

摘要

1.Repeatability and reproducibility coefficients of variation for the determination of acetaldehyde by headspace gas chromatog raphy-flame ionization detector (GC-FID) analysis ranged from 0.70 to 12% and 14 to 28%, respectively, and were judged un acceptable.rn2.Repeatability and reproducibility coefficients of variation for the determination of ethyl acetate by headspace GC-FID analysis ranged from 0.96 to 4.3% and 8.2 to 8.9%, respectively, and were judged acceptable.
