Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized. This standard is drafted by. Beijing Nonferrous Metal Research Institute. Participated in the drafting of this standard.

1 Scope

This standard specifies the method for the determination of trace elements in a high copper content, the determination of elements in Table 1. This standard applies to the determination of trace elements in a high copper content. Determination of the elements as follows. measurement range of sulfur and selenium for 10μg/kg ~ 5000μg/kg, the remaining elements of the measurement range of 1μg/kg ~ 5000μg/kg.

2 principle of the method

Sample as a cathode glow discharge in argon atmosphere, and the surface thereof is sputtered atoms from the sample into the glow discharge plasma In plasma ionized and then introduced into the mass spectrometer. In each element isotope mass number punishable by default scan points and the integration time The corresponding peak integration, the resulting area is the peak intensity of element content by the formula (1) is obtained. When no standard samples, according to the instrument computer software The "typical relative sensitivity factor" automatically calculate the mass fraction of each element; when the standard sample, and the sample required by the same Analytical conditions, the ion source under test conditions and the structure of a standard sample was determined by independent relative sensitivity factor, the application of the relative sensitivity Factor to calculate the mass fraction of the elements.

3 Reagents and materials

Unless otherwise indicated, the reagents used in the analysis are excellent pure; water used as a water. 3.1 nitric acid (11). 3.2 copper standard sample, measured elements mass fraction of between 50μg/kg ~ 500μg/kg. 3.3 Background monitoring instrument samples tested elements mass fraction lower than the above test sample 10 times. 3.4 Argon (purity ≥99.999%). 3.5 Nitrogen (purity ≥99.99%).

4 Instrument

4.1 high resolution glow discharge mass spectrometer, under the resolution mode resolution of up to 3000 to 4000, high-resolution mode resolution Rate of up to 9,000 to 10,000. 4.2 Determination of isotope and resolution shown in Table 1. Requirements isotope 63Cu spectrum measured peak intensity is not less than 5 × 109cps, peak shape in line with points Resolution requirements. ......
