1 Scope

This standard specifies the use of high-quality resolution Test Method for Determination of trace elements in high-purity aluminum glow discharge mass spectrometry. This standard applies to the determination of trace elements in high aluminum content. Determination of the elements in the range of 5.0 × 10-7% ~ 1.0 × 10-3% (Ω%).

2 Method summary

The specimen as a cathode is mounted to the plasma discharge chamber, an inert gas (argon) at high pressure generated from the ionized Son hit the sample surface to make it happen sputtering, sputtered from the surface of the sample out of the atom is ionized by double focusing magnetic sector mass spectrometer Focused ion beam is, in turn, is collected by a mass spectrometer detector. Each element in the mass number of scanning points and impose a preset integration time phase Should peak integration, the resulting area is the peak intensity. According to formula (1) is calculated by the instrument software impurity element content.

3 Reagents and materials

3.1 ethanol (ρ = 0.789g/mL), pure class distinctions. 3.2 hydrochloric acid (ρ = 1.19g/mL), pure class distinctions. 3.3 hydrochloride (11). Nitrogen 3.4 [ω (N2)] ≥99.99%. 3.5 Argon [ω (Ar)] ≥99.99%. 3.6 deionized water. resistivity required to achieve 18.2MΩ · cm. 3.7 standard high purity materials. conditions permit, the use of high purity standard RSG relative sensitivity factor RSFx measured elements.

4 Instrument

4.1 high resolution glow discharge mass spectrometer (GDMS). mass resolution up to 9000. 4.2 machining equipment, enables the sample and reference samples into the desired geometry and a smooth surface.

5 Sample

5.1 with uniform and representative sample. 5.2 Sample should not take the surface of the base material, will be the bulk sample preparation, it requires at least a glow discharge for a smooth plane; sample Size requirements can be placed in a glow discharge specimen holder cavity and its smooth surface can cover the sample holder on the discharge hole; specimen thickness requirements After the sample into sample holder does not affect the ion source chamber is closed. ......
