    • PURPOSE: Provided is a detection method of bisphenol-A among foods or foods packing material which shows selective and superior sensitivity for gas chromatography(GC) or GC/mass spectrometer so that it provides optimal analysis condition for the GC/mass spectrometer. CONSTITUTION: The detection method of bisphenol-A among the foods or the foods packing material comprises the steps of: (i) extracting bisphenol-A from the foods or the foods packing material in organic solvent and treating in sodium hydroxide; (ii) reacting with 100-1400μl of anhydrous acetic acid at 25-100deg.C for 5-20 minutes to produce derivatives of bisphenol-A; and (iii) analyzing concentration of bisphenol-A at the GC or the GC/mass spectrometer.
    • 用途:本发明提供一种食品或食品包装材料中的双酚A检测方法,其对气相色谱(GC)或GC /质谱仪显示选择性和优异的灵敏度,从而为GC /质谱仪提供最佳分析条件。 构成:在食品或食品包装材料中检测双酚A的方法包括以下步骤:(i)从食品或食品包装材料中用有机溶剂提取双酚-A并用氢氧化钠处理; (ii)在25-100℃与100-1400μl无水乙酸反应5-20分钟以产生双酚-A衍生物; 和(iii)分析GC或GC /质谱仪处双酚A的浓度。
