Sample preparation method and test method of glow discharge mass spectrometry ammonium paratungstate powder

The invention provides a sample preparation method and a test method of glow discharge mass spectrometry ammonium paratungstate powder. The method comprises the steps: forming a groove in the surface of a high-purity indium sheet, cleaning the indium sheet, transferring the ammonium paratungstate powder into the groove by using a cleaned medicine spoon, and compacting by using a press machine to obtain a sample to be tested. According to the sample preparation method, introduction of impurities can be fully avoided, the analysis time is shortened, and the accuracy of a test result is improved; and the test signal obtained by the test method is strong, and the sensitivity is high. 本发明提供一种辉光放电质谱仲钨酸铵粉末的制样方法以及测试方法，所述方法包括：在高纯铟片表面开设凹槽，对所述铟片进行清洗后，使用清洗后的药匙将仲钨酸铵粉末转移至所述凹槽中，使用压力机进行压实后得到待测样品。所述制样方法可以充分避免杂质的引入，缩短分析时间，提高测试结果的准确性；所述测试方法获得的测试信号强，灵敏度高。
