摘　　要：给出了一种ARL35 2 0型电感耦合等离子体光谱仪的技术改造方法。在“光栅摄谱仪升级改造技术”的基础上 ,结合该仪器的具体特点 ,对仪器光源进行了检修和局部改造 ;用现代通用型计算机取代原有的专用计算机 ,设计了光电测量控制电路 ;开发基于Windows操作平台的ICP实时分析软件技术。阐述了新编写研制的软件、硬件接口电路的结构及特点 ,并给出了仪器改造后的性能指标。ARL 3520 ICP spectrometer is successfully repaired. The ICP generator, which has been unable to work for years, is subjected to technical amelioration and is proved to give a steady plasma with good DL and RSD. The original dedicated computer is replaced with a modern PC computer and a new special purpose software is prepared on the Windows platform. A photoelectric measurement system and a controlling circuit are devised. A sketch description is made on the newly developed software, the main points of the hardware. Tables on the performance of the whole equipment are also given.
