摘　　要：采用HCS-878型高频红外碳硫分析仪将试料和助熔剂放入瓷坩埚,在氧气流中用高频感应炉加热熔融后,碳经燃烧生成二氧化碳,由氧气载至红外吸收池中。二氧化碳气体对红外吸收能量的变化遵循比尔定律。通过校正实验,碳含量的分析结果由显示器以百分含量直接显示出来。这方法分析速度快、精密度高、结果准确。In this paper, the HCS-878-type high frequency infrared carbon and sulfur analyzer is used to analyze the carbon content. The specimen and flux is put into the porcelain crucible to be heated and melted with high frequency induction furnace in a stream of oxygen. The carbon is transform to be carbon dioxide by combustion, and carried to infrared absorption pool by oxygen. Carbon dioxide gas on infrared absorption energy changes followes Bill＇s law. Through the cali- bration experiment, carbon content analysis result is displayed directly by percent content. The method is fast, high precision, and accurate.
