【摘要】 对AAS仪器的关键部件光源、分光系统与光电检测器件以及实验室研发的CS-AAS仪器装置,近年来取得的进步进行了评述,结合2004年由德国Analytik jena AG公司在世界上首次推出ContrAA 300型顺序扫描连续光源火焰原子吸收光谱商品仪器,对CS-AAS仪器装置的发展现状与未来作了分析讨论。此外,还对二极管激光器光源进入AAS领域后引起的变化和各种小型、微型原子化器的出现所兴起小型专用AAS实验仪器装置,以及一次测量背景校正技术的商品化等等作了介绍。更多还原

【Abstract】 The recent advances of the key parts such as sources,spectrometers and photoelectric detectors as well as continuum source-atomic absorption spectrometer(CS-AAS) have been reviewed in this paper.The present and future of commercial CS-AAS was discussed combined with sequential scanning flame atomic absorption spectrometer type ContrAA 300 manufactured by Analytik jena AG company of Germary.The changes as a result from the introduction of diode laser source,micro-atomizer and one measurement technique of background correction into atomic absorption spectrometer as well as the appearance mini and micro atomic absorption spectrometer for special purpose were introduced.更多还原
