| 摘 要： | 对离子色谱法检测印刷电路板清洁度的IPC(电子电路互连和包装标准)方法做出了进一步改进,提出了水浴加热联合氮吹样品的前处理方法,有效的去除了异丙醇对测量的干扰,而且对样品进行了浓缩;对样品中的有机酸进行了有效的分离和检测。结果表明,该前处理方法干扰小,可以使检测结果更准确,检测限为3 ng/mL(以Cl–计)。

| Abstract: | The IPC’s test method on cleanness of printed circuit board were improved.Water bath-heater combined with nitrogen-blow was proposed as a disposal method of sample.Interference of isopropanol on measure was removed effectively,and the sample was concentrated.Weak organic acids in the sample were separated effectively and examined successfully.The results show that this disposal method could make the result more exact,and its interference is small.The detection limit is 3 ng/mL(Cl–). |
