运用气相色谱-质谱法测试电子产品中的多溴二苯醚

Measurement of PBDEs in Electronic Products Using GC-MS for the RoHS Directive

本文介绍了费用低的样品处理方法和气相色谱-质谱的仪器分析方法测试电子产品中的多溴二苯醚。保留时间锁定(RTL)技术帮助快速定性单个的同分异构体。选择离子监测模式(SIM)保证了很高的测试灵敏度。结果表明该方法对满足欧盟和中国的RoHS法规要求的测试十分及时、有用。

In this paper, low-cost and most suitable sample preparations and analytical methods forthe determination of PBDEs and PBBs in electronic products with the GC-MS （gaschromatography＂C mass spectrometry） are presented. Retention time locking （RTL） techniquewas used for quick identification of specific congeners, with selective ion monitoring （SIM） modefor mass spectrometry （MS） detection, resulting in higher detection sensitivity.The results presented herein should be useful and timing for compliancing the EU Rolls and China RoHS.
