GB/T 20975.37-2020 Methods for chemical analysis of aluminium and aluminium alloys—Part 37:Determination of niobium content
Abstract
This part of GB/T 20975 specifies the weight method of paper chromatographic separation and the inductively coupled plasma atomic emission spectrometry for determining the content of niobium in aluminum and aluminum alloys.
This part is applicable to the arbitral determination of the niobium content in aluminum and aluminum alloys. The determination range of the weight method of paper chromatographic separation is 15.00%~90.00%; the determination range of the inductively coupled plasma atomic emission spectrometry is 0.050%~15.00%.
