测定葡萄酒中合成着色剂含量的不确定度评定

Uncertainty Evaluation for Simultaneously Determining Concentration of Four Synthetic Colours in Wine

通过对葡萄酒比对样品中四种合成着色剂同时测量的不确定度分析,建立了高效液相色谱梯度洗脱法同时测量多种组分不确定度的评定方法,并对测量过程中不确定度来源进行了详细分析和逐层合成。这种方法对液相色谱、气相色谱同时测定多组分不确定度评定具有重要的参考价值。

Based on analyzing the measurement of four synthetic colours in wine comparison sample, the uncertainty evaluation method of simultaneously determining concentration of multiple components by High Performance Liquid Chromatography（HPLC） was established. The sources of uncertainty were analyzed to compose steps for whole determination procedure. The method has large reference value for the uncertainty evaluation of simultaneously determining multiple components by HPLC and gas Chromatography（GC）
