A simple method has been devised for the analysis of di-(2-ethylhexyl)phthalate (DEHP) in human placenta which relies entirely on three rapid partition steps prior to gas chromatography with electron capture detection. The use of adsorption chromatography with all its attendant disadvantages for sample clean-up is eliminated in this procedure. Placental samples taken from women who had given birth to a normal baby contained 0.06 +/- 0.02 ppm of DEHP. The principal limitation of this method, and of any others, is the high blanks given by laboratory equipment and solvents. The reduction of contamination to workable levels is described.
已设计出一种简单方法用于分析人胎盘中的邻苯二甲酸二（2-乙基己基）酯（DEHP），该方法完全依赖于在气相色谱-电子捕获检测之前的三个快速分配步骤。此程序消除了使用吸附色谱及其伴随的所有用于样品净化的缺点。从分娩正常婴儿的妇女身上采集的胎盘样本中含有0.06±0.02 ppm的DEHP。该方法以及任何其他方法的主要局限性在于实验室设备和溶剂产生的高空白值。描述了将污染降低到可行水平的方法。
