目前,有色金属材料及其他化合物中硫量的分析方法多为两段式,即高含硫试样为一种,低含硫试样为另一种,原因是灵敏度高的方法用于测定高含硫试样时精密度不够,而宜于高含硫试样的测定方法却又缺乏足够的灵敏度。两种方法检出手段大不相同,分离措施亦大相径庭,给分析工作者带来不便。 At present, the non-ferrous materials and other compounds in the analysis of sulfur content are mostly two-stage, that is, a sample of high sulfur content, low sulfur content of the sample to another, because the sensitivity of the method used to determine the high Sulfur content of the sample is not enough precision, but suitable for high sulfur content of the test method but lack of sufficient sensitivity. The means of detection of the two methods are very different and the separation measures are very different, which brings inconvenience to the analysis workers.
