针对SH/T0711-2002汽油中锰含量测定法(原子吸收光谱法)中使用氯化锰(Mn Cl2·4H2O)作为标准物质时引起的偏差,进行偏移校正,所得结果在能力验证测试中令人满意,解决了氯化锰作为标准物质在实际测量中存在偏差的难题。
Deviations caused by the use of manganese chloride (Mn Cl2 · 4H2O) in the determination of manganese in SH / T0711-2002 gasoline (atomic absorption spectrometry) as the reference material were offset and corrected. The results were validated in the proficiency testing Satisfaction of people, to solve the manganese chloride as a standard material in the actual measurement of the existence of deviation problems.
