研究了辉光放电质谱法（GDMS）直接分析铂粉的适用性。通过分析掺杂有宽浓度范围内多种元素杂质的Pt样品，确定了不同感兴趣元素的相对灵敏度因子（RSF）。这些RSF用于量化分析良好表征的Pt粉末所获得的结果。研究表明，对于这种样品类型，GDMS可实现约10-15%的准确度和5-10%的重复性。GDMS的分析优值与通常用于测定铂的其它光谱技术进行了比较。GDMS具有样品制备简单、分析灵敏度高、分析速度快等优点。
A study was carried out to evaluate the applicability of glow discharge mass spectrometry (GDMS) for the direct analysis of platinum powder. The relative sensitivity factors (RSF) for the different elements of interest were determined by the analysis of Pt samples doped with impurities of several elements in a broad concentration range. These RSFs were used to quantify the results obtained for the analysis of a well characterized Pt powder. The investigation illustrated that an accuracy of about 10–15% and a repeatability of 5–10% are achievable with GDMS for this sample type. The analytical figures of merit of GDMS were compared with those of other spectrometric techniques normally applied for the determination of platinum. The simple sample preparation, sensitivity and speed of analysis were found to be valuable assets of GDMS.
