自Walsh于1953年首先建立原子吸收光谱分析技术以来,至今已有二十多年的历史。由于这项分析技术具有多方面的优越性,现已在各个领域中,得到了广泛的应用。就近年来国内外发表的文献资料看,原子吸收光谱分析正向着绝对分析目标发展。提高火焰原子吸收分析法的精密度和灵敏度的关键之一,决定于雾化器的性能,而雾化器的指标与它本身在工作状态下,所产生的气溶胶、雾滴粒度以及不同粒度所占百分数等有密切关系。因此,继续改进火焰原子化系统,成为文献中经常探讨的重要内容。
Since Walsh first established atomic absorption spectrometry in 1953, it has been more than twenty years old. Due to the superiority of this analytical technique in many aspects, it has been widely used in various fields. In recent years, literature published at home and abroad, atomic absorption spectrometry analysis is toward absolute development of the target. One of the keys to improving the precision and sensitivity of flame atomic absorption spectrometry depends on the performance of the nebulizer. The nebulizer’s indicator, itself, at work, produces aerosols, droplet sizes, and different particle sizes The percentage is closely related. Therefore, to continue to improve the flame atomic system, has become an important part of the literature often discussed.
