我们在用燃烧中和法测定样品硫的含量时,发现与硫酸钡重量法他分析结果系统偏低。造成这一系统误差的原因主要是分析方法和仪器装置上的问题,其次与操作人员技术水平有关。虽然对仪器装置和操作方法进行了尽可能的改进,但仍然没有明显的效果。因此,一般采用校正系数法来校正燃烧法的测定结果。关于校正系数法的校正系数,有关文献尚无详述,习惯上往往采用标样对照试验所得到的比例关系,作为改正分析结果的校正系数。如安徽省化工地质队化验室,即以一个标样 (鄂铜高全硫Ts=7.01％)用燃烧法作了106次平行测定,取其重合次数最多的一个值 (Ts=6.80％,n=32,表1) 来求取体正系数::
When we measured the sulfur content of the sample by the combustion neutralization method, we found that the results of the analysis with barium sulfate gravimetric method were low. The main reason for this systematic error is the analysis of the methods and equipment on the device, followed by the technical level of the operator. Although the instrumentation and methods of operation have been improved as much as possible, there is still no significant effect. Therefore, the correction factor method is generally used to correct the measurement result of the combustion method. The correction coefficient of the correction factor method, the literature has not described in detail, the customary use of standard control often proportional relationship between the test as a correction factor to correct the analysis results. Such as chemical geology team laboratory in Anhui Province, that is a standard sample (E copper high total sulfur Ts = 7.01%) by combustion method made 106 parallel determination, whichever coincidence number of the most value (Ts = 6.80%, n = 32, Table 1) to find the body positive coefficient ::
