Description
A method is presented for the determination of niobium, tantalum and tungsten in steel and non-ferrous alloys, based on hydrolysis with sulphurous acid followed by X-ray fluorescence measurements. The limit of determination is about 0.002% and the standard deviation is 0.002 at the 0.05% level. Results below 0.01% by this method are only semiquantitative. (author)
