A study on the determination of trace boron in steel by ARL-4460 spark OES is
discussed in this paper The experiment results show that the spectrum
background of boron should be kept stable under analysis condition controlled
Therefore, a good accuracy and precision can be obtained and the method can
meet the requirement of technology of steel plate used for automobil

性質:以火花放電作爲發射光譜分析的激發光源時所得到的光譜。該光譜有電極及試樣物質所産生的離子線和原子線,也有離子和電子複郃時所産生的連續光譜。後者是搆成火花光譜背景的主要原因。由於火花光源的激發溫度高,故離子線較多。它多用於高含量金屬、郃金和難激發元素的定量分析。
