质量控制图在杜马斯燃烧法测定奶粉中蛋白质的应用

Application of Quality Control Chart in the Dumas Combustion Method for the Determination of Protein in Milk Powder

将质量控制图应用于杜马斯燃烧法测定奶粉中的蛋白质含量中,选用X-图(均值图)和γ%-图(极差图)对质量控制样品的蛋白质含量检测结果进行分析,判断数据结果是否处于受控状态,探讨质量控制图在杜马斯燃烧法测定奶粉中蛋白质含量中的应用。

The quality control chart is applied to the determination of protein content in milk powder by the Dumas combustion method,and the X chart(mean value chart)andγ%-Figure(range chart)analyze the protein content test results of control samples,judges whether the data results are under control,and discusses the application of quality control chart in the determination of protein content in milk powder by Dumas combustion method.
