新技术在国产原子吸收光谱仪器上的应用

我国原子吸收光谱仪已有30多年生产历史，在自动化程度等方面和国外还存在着不少差距，但到目前为止，共产销了近两万台，在国内产销量一直是上升势头，是何原因？本文介绍了如在石墨炉的横向加热，石墨炉功率控温等新技术在国产原子吸收光谱仪上的应用。

Application of New Technology in Atomic Absorption Spectrophotometer

It has been over 30 years since the first China atomic-made absorption spectrophotometer came into be-ing.Although there is a gap between the AAS(atomic absorption spectrophotometer)of China and some advanced coun-tries in its automation level,in the past 30 years,we also have produced and sold nearly 20 thousand AAS,and thenumberis still increasing rapidly.This review gives a brief introduction to the application of new technology such as hori-zontal heating,controlling temperature by power,etc,in atomic absorption speetrophotometer.
