为满足高放和中放废液成分分析的需要,建立了一套适应放射性操作的封闭式原子吸收分析系统,其安装示意图示于图1。本工作将市售的商品原子吸收分光光度计进行改造,使之与专门设计的手套箱联接,将仪器原有的石墨炉和自动进样器通过可移动的不锈钢小车安装在手套箱内。这样,进样和原子化的动作,及更换石墨管、石墨炉锥体的操作,都可在手套箱内进行,
In order to meet the needs of high-level and middle-level waste liquid composition analysis, a set of closed-end atomic absorption analysis system that is suitable for radioactive operation was established. The installation schematic diagram is shown in Fig.1. This work will be commercially available commodity atomic absorption spectrophotometer modified to make it with the specially designed glove box connection, the instrument original graphite furnace and autosampler through a removable stainless steel trolley installed in the glove box. In this way, the injection and atomization movements, and the replacement of graphite tube, graphite furnace cone operation, can be carried out in the glove box,
