摘要:

建立高效液相色谱法测定葡萄酒中山梨酸含量的数学模型,全面分析不确定度来源并进行评估计算。影响测量结果不确定度的因素主要有标准曲线配制所使用量具的校准及样品测试过程中重复性实验两项。葡萄酒中山梨酸含量测定结果可表示为(70.4±2.7)mg/kg,包含因子k=2。

关键词: 高效液相色谱法, 葡萄酒, 山梨酸, 不确定度

Abstract:

The sources of uncertainty in high performance liquid chromatography (HPLC) determination of sorbic acid in
wine were fully analyzed according to the mathematical model. The uncertainties were mainly attributed to the calibration of
measuring tools used in the preparation of standard curve, and the repeated experiments in the determination. The content of
sorbic acid in wine could be shown as (70.4 ± 2.7) mg/kg (k = 2).

Key words: high performance liquid chromatography (HPLC), wine, sorbic acid, uncertainty
