由于氢化物原子吸收法具有较高的测定灵敏度,这种技术的应用日益广泛。作为氢化物法的原子化器,文献中曾使用过电加热或火焰加热的石英管、氩-氢或氮-氢火焰、氧化亚氮-乙炔焰、空气-乙炔焰、空气-氢、石英管中的氢氧焰以及石墨炉等。这些原子化器虽然各有所长,但是,在使用加热石英管时,原子化的机理比较复杂,可形成氢化物元素间的气相干扰比较严重,在使用过程中石英管的特性会逐渐变坏,灵敏度下降。使用空气-乙炔、氧化亚氮-乙炔
Due to the high sensitivity of hydride atomic absorption spectrometry, the use of this technique is becoming more widespread. As a hydride atomizer, quartz tubes, argon-hydrogen or nitrogen-hydrogen flame, nitrous oxide-acetylene flame, air-acetylene flame, air-hydrogen, quartz tube In the oxyhydrogen flame and graphite furnace. Although these atomizers have their own advantages, the mechanism of atomization is complicated when the quartz tube is heated, and the gas phase interference between the hydride elements is rather serious. The characteristics of the quartz tube gradually deteriorate during use , The sensitivity decreases. Use air - acetylene, nitrous oxide - acetylene
