本文讨论了石墨炉原子化器中管材料的性质和反应能力及其对分析灵敏度和准确度的影响.标准石墨,热解石墨和玻璃碳的表面性质和反应能力是不同的.而影响反应能力的重要因素是它们的宏观和微观的结构差异.全热解石墨和玻璃碳是各向异性的,具有较强的抗化学腐蚀能力。对几个元素在普通石墨管,热解石墨管和玻璃碳管中的灵敏度进行了比较,热解石墨管有最好的灵敏度. This article discusses the properties and reactivity of tube materials in a graphite furnace atomizer and their impact on analytical sensitivity and accuracy.The surface properties and reactivity of standard graphite, pyrolytic graphite and glassy carbon are different, Of the important factor is their macroscopic and microscopic structural differences.The pyrolytic graphite and glassy carbon are anisotropic and have strong resistance to chemical corrosion. The sensitivity of several elements in ordinary graphite tubes, pyrolytic graphite tubes and glassy carbon tubes was compared, and pyrolytic graphite tubes had the best sensitivity.
