本文介绍了用石墨杯作为原子化器,对钠原子进行了激光增强电离光谱研究。观察了诸因素对信号强度的影响。绘制了钠的标准曲线,含量范围为5×10~(-9)g—2×10~(-7)g。当钠为5×10~(-3)g时,相对标准偏差为18.5％。
In this paper, a graphite cup as a atomizer is introduced to study the sodium atom by laser enhanced ionization spectroscopy. Observed the impact of various factors on the signal strength. The standard curve of sodium was drawn, with the content range of 5 × 10 ~ (-9) g-2 × 10 ~ (-7) g. When sodium is 5 × 10 -3 g, the relative standard deviation is 18.5%.
