特殊医学配方乳粉中硒测定方法探讨
|
摘要
探讨原子荧光光谱法和电感耦合等离子体质谱法测定特殊医学用途婴儿配方乳粉中硒含量的结果差异和方法影响因素。电耦合等离子体质谱法的测定结果较原子荧光光谱法的测定结果高10%左右,电耦合等离子体质谱法影响因素主要在于质谱多原子离子干扰和碳增益效应,而原子荧光光谱法主要受硒的形态释放程度和还原反应效率制约。电感耦合等离子体质谱法在测定过程上较原子荧光光谱法操作简便,而电耦合等离子体质谱法的测定结果普遍高于原子荧光光谱法的测定结果。
It was to investigate the difference between atomic fluorescence spectrometry(AFS) and inductively coupled plasma mass spectrometry(ICP-MS) in the determination of selenium content in formula milk powder for special medical purposes intended for infant and the influencing factors. The results of ICP-MS were about 10% higher than that of AFS. The main influencing factors of ICP-MS were polyatomic ion interference and carbon gain effect, while AFS was mainly restricted by the degree of selenium form release and the reduction reaction efficiency. ICP-MS was more convenient than AFS, and the results of ICP-MS were generally higher than that of AFS.
