| description | The invention discloses a method for determining content of carbon and sulfur in high-purity gold by employing a high frequency-infrared absorption method, which takes a high frequency-infrared carbon sulfur analyzer as a measuring instrument. According to the invention, CO2 and SO2 have strong characteristic absorption band at positions of 4.26 [mu]m and 7.4 [mu]m, CO2 and SO2 content can be analyzed by measuring the gas absorption intensity, fitting is carried out by primary linear relationship, and a work curve is made, and the percentage content of the carbon and sulfur content in a detected sample can be indirectly determined. The method has the characteristics of easy and fast operation, high precision, low cost and strong applicability.
本发明公开了种采用高频红外吸收法测定高纯金中碳硫含量的方法以高频红外碳硫分析仪作为测量仪器，利用CO及SO分别在4.26μm和7.4μm处具有较强的特征吸收带这特性，通过测量气体吸收强度分析CO和SO含量，以次线性关系进行拟合，制作工作曲线，间接确定被测样品中碳、硫元素的百分含量。该方法具有操作简单快捷、精准度高、成本低、适用性强的特点。 |
