中、小型工厂试验室时常遇到非大宗但经常进行化验的样品。例如我厂高强度合金铸铁中磷、硅、镍、铜、钼等元素测定,隔几天来一个试样。使用标准曲线法不太适宜。过去我们为保证化验质量,采用平行带一个以上标样进行分析,感到手续繁复,且浪费标样、药品,也影响分析速度。 Medium and small factory laboratories often encounter non-bulk but often test samples. For example, I plant high-strength alloy cast iron phosphorus, silicon, nickel, copper, molybdenum and other elements measured every few days to a sample. The use of standard curve method is not appropriate. In the past we in order to ensure the quality of laboratory tests, using parallel with more than one standard for analysis, feel complicated procedures, and the waste of standard samples, drugs, but also affect the analysis speed.
