摘要
设计开发了一套电感耦合等离子体发射光谱仪(ICP-OES)高电离能元素进样系统.系统既保留了ICP-OES原有的检测功能,又利用超声波振动空化作用的物理方法与氢化反应的化学方法有机结合,有效增加单位体积内待测元素检测浓度,使高电离能元素的检测灵敏度在原有基础上提高3~5倍.系统的研制扩展了ICP-OES关于高电离能元素的检测功能.
A set of high ionization energy element sample injection system of inductively coupled plasma optical emission spectrometry(ICP-OES)was designed and developed.The system not only retains the original detection function of ICP-OES,but also combines the physical method of ultrasonic vibration cavitation with the chemical method of hydride generation,to effectively increase the detection concentration of elements to be measured in an unit volume,so that the detection sensitivity of high ionization energy elements can be increased by 3~5 times on the original basis.The development of the system extends the detection function of ICP-OES for high ionization energy elements.
