Methods for chemical analysis of high purity niobium Determination of trace elements Inductively Coupled Plasma Mass Spectrometry

1 Scope

This standard specifies the niobium of high purity lithium, beryllium, boron, magnesium, titanium, vanadium, manganese, iron, cobalt, nickel, copper, zinc, gallium, arsenic, strontium, zirconium, tantalum, molybdenum, cadmium, tin, antimony, Hafnium, tungsten, lead, and the determination of bismuth content. This standard applies to the determination of trace impurities in high purity niobium. Measurement range. 0.0001% to 0.010%.

2 Method summary

Sample with nitric acid and hydrofluoric acid dissolved rhodium internal standard calibration, inductively coupled plasma mass spectrometry directly it determined by the curve Method to calculate the concentration of each element to represent the mass fraction measurement results.

3 Reagents

Unless otherwise indicated, the reagents used in the analysis are excellent pure; the water is a water. 3.1 Hydrofluoric acid (ρ = 1.16g/mL). 3.2 nitric acid (ρ = 1.42g/mL). 3.3 nitric acid (11). 3.4 lithium, beryllium, boron, magnesium, titanium, vanadium, manganese, iron, cobalt, nickel, copper, zinc, gallium, arsenic, strontium, zirconium, tantalum, molybdenum, cadmium, tin, antimony, hafnium, tungsten, lead, bismuth and rhodium unit Prime standard stock solution (national standard sample/national standard), the concentration of 1000μg/mL. 3.5 mixed standard solution A. Pipette each element separately 10.00mL standard stock solution (except rhodium element) (3.4) in 1000mL plastic Flask, additional 2mL of hydrofluoric acid (3.1), 20mL of nitric acid (3.3), dilute to the mark and mix. This solution 1mL containing lithium, beryllium, Boron, magnesium, titanium, vanadium, manganese, iron, cobalt, nickel, copper, zinc, gallium, arsenic, strontium, zirconium, tantalum, molybdenum, cadmium, tin, antimony, hafnium, tungsten, lead, bismuth each 10μg. 3.6 mixed standard solution B. Pipette 10.00mL mixed standard solution A (3.5) in 100mL plastic flask, nitric acid supplemented with 2mL (3.2), dilute to the mark and mix. This solution 1mL containing lithium, beryllium, boron, magnesium, titanium, vanadium, manganese, iron, cobalt, nickel, copper, zinc, gallium, arsenic, strontium, Zirconium, tantalum, molybdenum, cadmium, tin, antimony, hafnium, tungsten, lead, bismuth each 1μg, the time is now equipped with. 3.7 rhodium internal standard solution. Pipette 1.00mL rhodium-element standard stock solution (3.4) in a plastic 1000mL volumetric flask, dilute to the mark with water Degree, and mix. This solution 1mL rhodium-containing 1μg.
