前言辉光放电光源的稳定度高,只要有精度好的检测系统,可保证分析结果有很高的精密度。直接进行固体块样的合金组分元素分析,是这种光源的特长之一。用辉光放电光源作铝合金的分析,国外也有报导。因铝合金极易氧化,试样表面易形成氧化膜,所以试样不易产生正常的剥离,而且预燃时间往往很长又无规律,因而分析再现性不好。浅田庄太郎等认为铝合金的分析,用辉光放电光源是很困难的。他们在试验中还发现了第三元素的影响。试样中只要含有铜,溅射量就增大,使准确度变坏。Dogan研究了铜-
Introduction Glow discharge light source of high stability, as long as the accuracy of the detection system can ensure that the analysis results have a high degree of precision. Directly solid-like alloy elemental analysis is one of the characteristics of this light source. With glow discharge light source for the analysis of aluminum alloy, there are also reports abroad. Due to the extremely easy oxidation of aluminum alloy, the sample surface is easy to form oxide film, so the sample is not easy to produce normal peeling, and the pre-burning time is often long and irregular, so the analysis reproducibility is not good. Asada Shintaro, etc. that the analysis of aluminum alloy, glow discharge light source is very difficult. They also found the third element in the experiment. As long as the sample contains copper, the sputtering amount increases, making the accuracy worse. Dogan studied copper -
