在任何检验中,检验结果都不是一个定数,人员、设备、时间不同,数据也有一定的变化。食品检验也不例外,检验数据是否准确可靠,以前用相对偏差表示,随着科学的发展国际、国家也对数据有一个更高的要求,那就是不确定度。本文通过高效液相色谱法对乳粉中蔗糖含量测定不确定度的计算方法为例,根据实际情况,建立以高效液相色谱法来测定乳粉中 In any test, the test results are not a fixed number, personnel, equipment, time is different, the data also have some changes. Food inspection is no exception, the test data is accurate and reliable, previously used relative deviation that with the scientific development of the world, the country also has a higher data requirements, that is uncertainty. In this paper, high performance liquid chromatography (HPLC) method for the determination of the uncertainty of the determination of sucrose content in milk powder as an example, according to the actual situation, the establishment of high performance liquid chromatography to determine milk powder
