GB/T 223.81-2007 Iron steel and alloy—Determination of total aluminum and total boron contents—Microwave digestion-inductively coupled plasma mass spectrometric method
1 Scope
This Part of GB/T 223 specifies a microwave digestion-inductively coupled plasma mass spectrometric method for the determination of the total aluminium and total boron contents in iron, steel or alloy.
This method is applicable to the determination of the total aluminium and total boron contents. Determination range: total aluminium content (m/m): 0.0005%~0.10%; total boron content (m/m): 0.0002%~0.10%.
