目前,广泛应用于大量区域化探样品分析的电弧水平电极撒样法光谱半定量分析,具有快速简便、易挥发和中等挥发元素的分析灵敏度高、重现性好等优点,但对一些难激发元素的测定灵敏度低、重现性差和受基体成分影响大。为克服这些缺点,我们制定了交流电弧- 低压火花水平撒样法,其灵敏度列于表1。 At present, it is widely used in semi-quantitative analysis of arc horizontal electrode scatter spectroscopy in a large number of regional geochemical exploration samples. It has the advantages of high sensitivity, good reproducibility, such as quick and easy, volatile and moderately volatile elements. However, The elemental assay has low sensitivity, poor reproducibility and is strongly influenced by matrix composition. To overcome these shortcomings, we developed a AC arc - low pressure spark level sprinkling method, the sensitivity is shown in Table 1.
