A method has been developed for determination of bisphenol A diglycidyl ether (BADGE) in 3 aqueous-based food simulants: water, 15% (v/v) ethanol, and 3% (w/v) acetic acid. BADGE is extracted with C18 cartridges and the extract is concentrated under a stream of nitrogen. BADGE is quantitated by reversed-phase liquid chromatography with fluorescence detection. Relative precision at 200 micrograms/L was 3.4%, the detection limit of the method was 0.1 micrograms/L, and recoveries of spiking concentrations from 1 to 8 micrograms/L were nearly 100%. Relative standard deviations for the method ranged from 3.5 to 5.9%, depending on the identity of the spiked aqueous-based food simulant.
已开发出一种方法，用于测定3种水基食品模拟物（水、15%（v/v）乙醇和3%（w/v）乙酸）中的双酚A二缩水甘油醚（BADGE）。用C18柱提取BADGE，提取物在氮气流下浓缩。采用反相液相色谱-荧光检测法定量BADGE。200微克/升时的相对精密度为3.4%，该方法的检测限为0.1微克/升，1至8微克/升加标浓度的回收率接近100%。该方法的相对标准偏差范围为3.5%至5.9%，具体取决于加标的水基食品模拟物的种类。
