原子发射光谱仪器的新进展

Technique Development for Atomic Emission Spectrometer

原子发射光谱仪器正不断向全谱直读功能发展 ,并向智能化、小型化、实用化、低分析成本方向发展。新型的台式及便携式手提直读光谱仪 ,采用光栅分光—CCD检测器系统 ,光谱焦距仅在 1 5～ 1 7cm ,具有全谱直读的分析功能 ,其性能不亚于传统的实验室直读光谱仪。具有小型、轻便 ,可以对多种金属进行近似定理分析 ,直接显示分析结果 ;可以进行金属类型 ,对 /错鉴别 ,快速分类和等级鉴别 ,适于现场分析 ,可以带到任何需要进行金属分类的现场。

The technique Development of Atomic Emission Spectrometers trend towards being whole spectrum direct_reading function,and develop to instruments with practicality and lower price have been put out in succession,Automatization and Intellectual ability of the instruments have been continuously improved;come forth New model desktop and portable Spectrometers,These spectrometers all apply grating dispersing_CCD detector system,with focus only 15_17cm and have whole spectrum direct_reading function.Although they are small_scale and light,their characteristics are not inferior to traditional laboratory direct_reading spectrometers.These spectrometers have the following functions:displaying analytical results and metal style directly,judging right or rough,quickly classifying and grade distinguishing.These spectrometers are suitable to be used on_site analysis and can be takeen to any places where metal distinguishing and metal classifying are necessary to be done reliably.They are one kind of the metal analyzers with whole new idea.
