Determination of high purity gallium oxide impurities Inductively Coupled Plasma Mass Spectrometry

1 Scope

This standard specifies the method for the determination of high-purity gallium oxide content of impurity elements. This standard applies to the determination of the high-purity gallium oxide, sodium, magnesium, calcium, titanium, vanadium, chromium, manganese, iron, nickel, cobalt, copper, zinc, tin, lead, indium content. Determination of the elements in the range (1 × 10-6)% ~ (4 × 10-5)%.

2 Method summary

The sample is dissolved by the acid mixture, prepared after the test solution by inductively coupled plasma mass spectrometry (ICP-MS) was measured to obtain the test element Number of prime quality signal. Impurity elements in the signal intensity of the mass number of the vertical axis, the concentration of the impurity element abscissa standard addition method work Curve, then calculate the mass fraction of the measured sample measured elements. Recommended using isotope mass number listed in Appendix A measuring element.

3 Reagents and materials
