发射光谱分析是一种比较成熟的分析方法,在现代分析方法中起着极其重要的作用。 发射光谱分析在近几年里的发展情况,特别是光谱分析的有关仪器的进展情况,可从文献中了解到,本文仅对化学光谱分析方法及其进展情况加以介绍。 通过化学方法从大量基体物质中把少量的待测元素分离到一较小体积中,再把富集物用发射光谱法进行测定,称为化学光谱法。 有下列情况需采用化学富集:(1)试样中待测元素含量过低,直接光谱法灵敏度不 Emission spectrum analysis is a relatively mature analytical method that plays an extremely important role in modern analytical methods. The development of emission spectroscopy in recent years, especially the progress of spectrometer related instruments, can be learned from the literature, this article only chemical spectroscopy methods and their progress to be introduced. By chemical methods from a large number of matrix material to be measured in a small amount of elements to be separated into a smaller volume, and then measured by emission spectrometry, known as chemical spectroscopy. There are the following situations need to use chemical enrichment: (1) the sample element to be tested is too low, the direct spectral sensitivity
