[Determination of trace elements in pure metal by optical emission spectrometry].
The important factor for trace concentration element analysis by optical emission spectrometry is detection limit, RSD, stability. Through study on analytical parameters of trace element in pure metal, it is found that the detection limit of element mainly depends on the choose analytical line and discharge type but bears no relation to reference. RSD and stability of analysis depend on analytical line pair(analytical line/reference line) and discharge type. The best analytical parameter will be selected to make quick and accurate analysis with this principle.
