摘要
米面及其制品中可能非法加入含卤素类增塑剂,目前鲜见检测方法的报道。本文应用气相色谱-质谱联用(GC-MS)同时检测氯化石蜡等9种含卤素类增塑剂。优化条件为:采用HP-5MS色谱柱;进样口温度280℃;载气1.2mL/min;色谱-质谱接口温度270℃;采用程序升温,起始柱温35℃,保留1min,以10℃/min升温至220℃,再以20℃/min升温至300℃,保留5min。该方法条件下,目标物质检测限在0.01μg/L^15mg/L,峰面积标准偏差均≤0.061,保留时间标准偏差均≤0.007,分离效果较好。
Rice and its products may be illegally added halogen-containing plasticizers,but detection methods rarely reported. In this paper,chlorinated paraffin and other 9 kinds of halogen-containing plasticizers were simultaneous detected by gas chromatography-mass spectrometry（GC-MS）. Optimum conditions were：using HP-5MS column,inlet temperature 280℃,carrier gas 1.2mL/min,chromatography-mass spectrometry interface temperature 270℃. Using temperature-programmed：starting column temperature 35℃,keeping 1min,at 10℃/min heating to 220℃,then 20℃/min heating to 300℃,keeping 5min. Under these conditions,the retention time was no more than 0.007,the standard deviation of peak area was no more than 0.061,detection limited of the of the9 kinds of halogen-containing plasticizers varied between 0.01μg/L^15mg/L. This method was well separated.
