Abstract

The advantages and disadvantages of neutron activation analysis (NAA) and inductively coupled plasma-source mass spectrometry (ICP-MS) for the analysis of biological materials is reviewed. Comparison is made between NAA (instrumental) and ICP-MS (conventional pneumatic solution nebulization and laser ablation) analysis of the biological reference material National Bureau of Standards (NBS) SRM 1577 Bovine Liver. Relatively good agreement is achieved between the results for the 18 elements analyzed by both techniques and those either certified or reported in the literature. Elemental concentrations for Li, Mg, Al, Ca, Cr, Mn, Fe, Cu, Zn, Br, Rb, and Cs are also reported for IAEA Mixed Human Diet (H9), NBS SRM 909 Human Serum, and NBS SRM 1577a Bovine Liver, analyzed by solution nebulization ICP-MS.

摘要

综述了中子活化分析（NAA）和电感耦合等离子体质源质谱法（ICP-MS）在生物材料分析中的优缺点。对国家标准局（NBS）SRM 1577牛肝这种生物参考物质进行了NAA（仪器法）和ICP-MS（传统气动溶液雾化和激光烧蚀）分析的比较。两种技术分析的18种元素的结果与文献中认证或报道的结果之间达成了相对较好的一致性。还报告了通过溶液雾化ICP-MS分析的国际原子能机构混合人类饮食（H9）、NBS SRM 909人血清和NBS SRM 1577a牛肝中锂、镁、铝、钙、铬、锰、铁、铜、锌、溴、铷和铯的元素浓度。
