气相色谱-原子发射光谱的CIC定量方法研究

Study of compound independent calibration by GC-AES

运用气相色谱-原子发射光谱所独有的化合物无关校正曲线法(CIC法),分别对P、C、As、S 4个元素通道进行实验,得出了误差规律,结果表明:当被测化合物的保留时间与标准物质相近,分子结构相似,定量结果的相对误差较小;保留时间相差较远,分子结构相差较多,则定量结果的相对误差就较大。如果在实验室标准物质缺乏的情况下,可以利用CIC方法进行定量。

The unique CIC method of AES was studied in the thesis. The error rules were concluded through the study of four element channels, such as P, C, As, and S. The result shows： the more similar retention time and molecular structure has, the more smaller the relative error has. Vice versa. The method is suitable for the situation of lack of standard compounds.
