摘要
用钨酸盐涂镀石墨管和ＮＨ４ＮＯ３基体改进剂直接测定血清中微量锗，消除基体干扰、显著改进灵敏度，准确度和精密度、相对标准偏差小于３６１。
Using a tungstatecoated graphite tube,trace germanium in serum samples was determined by Zeeman graphite AAS with NH4NO3 as a matrix modifier.The sensitivity of Ge can be significantly improved.The matrix interference has been removed.The relative standard deviation is less than 361%.The method is simple,rapid and accurate.
