关于乳粉中钙元素质控样品的研制及应用

该质控样品可广泛用于乳制品实验室乳粉中钙的含量测定、质量控制及检测项目的开展等。利用实验室日常检测乳粉样品进行乳粉中钙元素实物质控样品的制备,采用分装设备进行分装和包装、均匀性及稳定性统计学评价,实物质控样品赋值的研究、不确定度的确定。最终应用于企业实验室日常实验室质量控制、方法验证证实、期间核查等方面,质控样品的基质和企业实验室日常检测样品基质一致,检测结果更具有代表性。

Development and application of quality control samples of calcium in milk powder

The quality control sample can be widely used in the determination of calcium content in dairy laboratory milk powder, quality control and the development of testing items. Using laboratory routine test milk powder samples to prepare calcium material control samples in milk powder, using packaging equipment for packaging and packaging, statistical evaluation of uniformity and stability, research on the assignment of physical substance control samples, uncertain Degree determination. Finally, it is applied to the daily laboratory quality control, method validation and period verification of the enterprise laboratory. The matrix of the quality control sample is consistent with the daily test sample matrix of the enterprise laboratory, and the test results are more representative.
