石墨炉原子吸收法测定化探样品中痕量金——石墨管使用次数对分析准确度的影响
Determination of Trace Gold in Stream Sediments by Graphite Furance Atomic Absorption Spectrometry-The effect of Analytical Accuracy on Graphite Tube Used Numbers
【摘要】 本文报道了普通石墨管在化探样品中痕量金测试过程中,分析准确随石墨管使用次数的增加而变化的现象,研究了其引起的主要原因,简述了这类问题解决的办法。
【Abstract】 The phenomena that analytical accuracy is changed with the crease of the used numbers of general graphite tubes at the determination of trace gold in stream sediments, and its main reasons of carse are investigated. The solving methods of this phenomena are proposed.
