摘要
采用钢、铁标样校正工作曲线,高频红外碳硫分析仪测定金属锰中碳、硫的含量,方法快捷、灵敏、准确,检测下限可达C:0.0020%、S:0.0025%(质量百分数),相对标准偏差均小于2%。
A rapid, sensitive and accurate method in which steel and iron standard sample is used to correctthe operating characteristic and high frequency IR analyzer to determine carbon and sulfur contents in metallicmanganese is described. It allows a lower detection limit of 0.0020%C and 0.0025%S (mass fraction) and theRSD are all less than 2%.
