摘要
采用高效液相色谱仪配合可变单波长紫外检测器,通过波长程序的设置,对7种合成着色剂进行分析检测,最小检出浓度可达0.010μg/mL,重复性均在3%以内,满足国家标准的要求。本方法既保证7种合成着色剂的高灵敏度检出,又无需使用较为昂贵的二极管阵列检测器,为食品中合成着色剂的测定提供有效途径,适合在各级尤其是基层检测机构推广。
In this work,seven kinds of artificial pigment have been analyzed by HPLC with UV/VIS variable wavelength UV detector programmed wavelength method provide a high analysis performance.All target compounds got good detection limits and the reproducibility was in 3%.And also,using UV/VIS variable wavelength UV is more economical compared with diode array detector.
