GB/T 223.80-2007
Scope
This part of GB/T 223 specifies the method for the determination of bismuth and arsenic in steel and alloys by hydride generation-atomic fluorescence spectrometry. This method is suitable for the determination of bismuth and arsenic in steel and nickel-based alloys. The mass fraction range of bismuth determination: 0.000 05% ~ 0.01%; the mass fraction range of arsenic determination: 0.000 05% ~ 0.01%
