1955年 Walsh 对原子吸收光谱分析法的原理和应用进行了介绍,至今十余年来,火焰原子吸收分光光度法已日趋完善,特别是1965年采用乙炔-笑气火焰后,使火焰法分析的元素由三十多个增到七十多个从而更加引起人们的注意。火焰原子吸收分光光度计的全世界年产量,从1964年以前仅四百台,到1972年增至一万七千到一万八千台。发展之快,在仪器分析中也是罕见的。随着科学技术的发展,对分析提出了更高要求。例如半导体材料要求分析10~(-7)到10~(-10)原子比杂质,环境污染研究中要求分析水中10~(-7)到10~(-10)克/毫升和一立方米空气中10~(-5)到10~(-8)克有害杂质,医院要求在小于十分之一毫升血中分析多种10~(-7)克/毫升以下痕量元素,生物和生化研究中要求知道痕量金属的催化触媒作用,尖端部门要求知道许多高纯材料的纯度,等等。有许多分析手段能解决上述问题,对此文献有过
In 1955, Walsh introduced the principle and application of atomic absorption spectrometry. For more than ten years, Flame Atomic Absorption Spectrophotometry has become more and more perfect. Especially after using acetylene-nitrous oxide flame in 1965, The number of elements increased from thirty to more than seventy so as to attract more attention. Flame atomic absorption spectrophotometer worldwide annual production, from only 4 hundred before 1964, to 1972 to 17,000 to 18,000. Rapid development is also rare in instrumental analysis. With the development of science and technology, the analysis put forward higher requirements. For example, semiconductor materials require the analysis of impurities in the order of 10-7 (-10) atomic percent, and environmental pollution studies require the analysis of 10-7 (-7) to 10-10 g / ml of water and one cubic meter of air In the range of 10-5 to 10-8 grams of harmful impurities, the hospital is required to analyze a wide range of trace elements below 10-7 grams / milliliter in less than one tenth of a milliliter of blood for biological and biochemical studies Requires knowledge of the catalytic role of trace metals, cutting-edge departments require knowledge of the purity of many high-purity materials, and more. There are many analytical tools to solve the above problems, which have been documented in this article
