近年来有机元素微量分析愈来愈趋向于自动化。仪器分折方法很多,但大多采用燃烧和燃烧产物用色谱分离、热导检测相结合的方法。目前国内、外已有些单位采用不用称量样品的方法进行有机元素微量分析。这种方法是利用已知化合物作为标准,将其得到的数据作为参考,由色谱的分析信号和灵敏度,直接求得化合物的原子比,由此就得出了不用称量样品而测得碳、氢、氮、氧、硫的原子比,通过原子比而求
In recent years, trace element analysis of organic elements tends to be more and more automated. There are many ways to analyze instruments, but most of them use methods of combining combustion and combustion products with chromatographic separation and thermal conductivity detection. At present, some units at home and abroad have adopted the method of not weighing the samples for the trace element analysis of organic elements. This method uses the known compound as a standard and uses the obtained data as a reference to directly determine the atomic ratio of the compound from the analytical signal and the sensitivity of the chromatogram. Thus, the carbon is measured without weighing the sample, The atomic ratio of hydrogen, nitrogen, oxygen and sulfur is determined by the atomic ratio
