本刊讯日前,在土耳其伊斯坦布尔召开的国际纯粹与应用化学联合会同位素丰度与原子量委员会(IUPAC CIAAW)会议上,由中国计量科学研究院化学分析所王军创新团队建立的硒同位素丰度校正质谱法测量工作被评为最佳测量,采用该方法测量的硒原子量(78.971(8))被采纳为新的硒原子量国际标准值。此次新的硒原子量测量采用了近年国际公认的同位素权威测 Recently, at the meeting of IUPAC CIAAW held in Istanbul, Turkey, the selenium isotope abundance correction set up by the innovation team of Wang Jun of Institute of Chemical Analysis of China National Institute of Metrology The mass spectrometry measurement was rated as the best measurement. The amount of selenium (78.971 (8)) measured by this method was adopted as the new international standard of selenium. The new selenium atomic weight measurement using internationally recognized isotope authoritative measurement
