摘要

采用气相色谱法(GC)测定了花青醛含量.花青醛质量浓度在0.2~1.8 g/mL范围内与峰面积呈良好线性关系，线性方程为y=5884.7x-264.62（r2=0996.1）.检出限（信噪比为3）和定量限（信噪比为10）分别为0.02 g/L和0.05 g/L.添加3个浓度水平的回收率为95.5%～101.5%，相对标准偏差为0.74%～2.91%.将此方法应用于3批实际样品分析，获得了令人满意的结果.

气相色谱法花青醛含量测定

Abstract:

The content of florhydral was determined by gas chromatography (GC).The mass concentration of florhydral showed a good linear relationship with the peak area in the range of 0.2~1.8 g/m,and the linear equation was y=5884.7x-264.62 (r2=0.9961).The limits of detection (signal-to-noise ratio is 3) and the quantification limit (signal-to-noise ratio is 10) were 0.02 g/L and 0.05 g/L,respectively.The recoveries were 95.5%～101.5%,and the relative standard deviations (RSD) were in the range of 0.74% ~ 2.91%.The method has been applied to the analysis of 3 batches of actual samples with satisfactory results.
