摘要 依据《标准样品工作导则》(GB/T 15000-94)技术要求,以苯作为溶剂,采用重量法配制甲基汞和乙基汞环境标准样品。经过均匀性、稳定性检验后,由8家实验室用气相色谱法和冷原子吸收分光光度法协作定值,经数理统计检验,给出了这两种标准样品的标准值和不确定度。 Methyl mercury and ethyl mercury environmental reference materials (ERMs) were developed using gravimetric method with benzene as solvent according to GB/T 15000-94. After the homogeneity and stability being tested, the ERMs certificated value and uncertainty were given after mathematical statistics of all data from eight labs using gas chromatography and cold vapour atomic absorption methods.
