使用玻璃碳材料作热解涂层石墨管的恒温平台,利用玻碳材料抗化学腐蚀能力强、使用寿命长和孔隙率低等特点,克服了玻碳管使用温度受电源装置的限制及影响中等蒸发元素测定等问题,初步研究了典型易蒸发元素Cd和中等蒸发元素Cu在玻璃平台上的分析性能;比较了不同规格玻璃碳平台与标准石墨平台间的差异以及它们之间抗基体干扰的能力;用扫描电子显微镜观察了它们的表面状态。
The use of glassy carbon material as pyrolysis coating graphite tube temperature platform, the use of glassy carbon material resistance to chemical corrosion, long life and low porosity, to overcome the use of carbon nanotubes by the power supply device limits and the impact of medium Evaporation element determination and other issues, preliminary analysis of the typical easy-to-evaporate elemental Cd and moderately evaporated elemental Cu on the glass platform performance; comparison between different specifications of glassy carbon platform and the standard graphite platform and their resistance to interference between matrix ; Their surface state was observed with a scanning electron microscope.
