摘要
采用了超声波提取法对RoHS检测样品前处理,以气相色谱—质谱法定量分析,通过与索氏提取法、标准值比较验证其可行性。t值检验结果无显著性差异,因此符合要求。超声波提取法简便快捷,准确有效,可用于RoHS检测有机类样品前处理。
In this paper, ultrasonic extraction on the sample processing, and GC -MS for quantitative analysis are used. Compared with Soxhlet extraction and standard sample, this method is verified to be feasible. The results of t - test show no significant differences. Ultrasonic extraction is an effective pretreatment for RoHS testing.
