Foreword

YS/T 229-2013 "high purity chemical analysis of lead" is divided into four parts. --- Part 1. silver, copper, bismuth, aluminum, nickel, tin, magnesium, and iron - Determination of chemical spectroscopy; --- Part 2. Determination of arsenic content by atomic fluorescence spectrometry; --- Part 3. Determination of antimony content - Atomic Fluorescence Spectrometry; --- Part 4. Determination of trace element contents of glow discharge mass spectrometry. This is Part 4 YS/T 229's. This section 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 section is responsible for drafting unit. Dongfang Electric Group Emei Semiconductor Materials Research Institute. Participated in the drafting of this section. Beijing Nonferrous Metal Research Institute, New Material Technology Co., Ltd. Jinchuan. The main drafters of this section. Wang Panfeng, Wenying, Sun Ping, Liu, Qiu Ping, Xu Shunbo. Methods for chemical analysis of high purity lead Part 4. Determination of trace element contents Glow Discharge Mass Spectrometry

1 Scope

This section YS/T 229 specifies the method for determination of trace elements in high purity lead content, the determination of elements in Table 1. This section applies to the determination of trace elements in high purity lead content. Determination of the elements as follows. measurement range of sulfur and selenium for 100μg/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, the surface atoms to be sputtered from the sample and enters the glow discharge plasma, the plasma Ionized and then introduced into the mass spectrometer. In each element isotope mass number punishable by default scan points and the integration time of the peak corresponding plot Min, the resulting area is the peak intensity. When semi-quantitative analysis, computer software instrument based on "typical relative sensitivity factor" Auto Calculate the mass content of each element; when quantitative analysis is required by the sample in the same assay conditions, the structure of the ion source and measure Under standard test conditions for independent samples was determined by the relative sensitivity factors, the application of the relative sensitivity factor to calculate the mass of each element content.

3 Reagents and materials

Unless otherwise indicated, the reagents used in the tests were excellent pure; the water used is deionized water, the resistivity required to achieve 18.2MΩ/cm. 3.1 Nitrogen (φ≥99.99%). 3.2 nitric acid (11). 3.3 lead standard samples, the measured element mass content of between 50μg/kg ~ 500μg/kg. 3.4 lead blank sample, the element content is less than the requirements of the test sample under test element content more than 10 times.

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 machining equipment, the sample can be prepared as desired geometry (block or rod), the sample to be analyzed surface should be flat and smooth. 4.3 Determination of Isotopic and resolution shown in Table 1, the requirements of 208Pb isotope peak intensity spectrum measured is not less than 5 × 109cps, peak pictogram Together resolution requirements. ......
