摘要
本文以用途较为广泛的邻苯二甲酸、丁二酸和顺丁烯二酸为研究对象,探讨了它们在SF-96柱上的色谱性能以及定量分析的线性响应关系。
The gas chromatographic behavior of a -phthalic acid, succinic acid and maleic acid on an SF-96 column was studied. The organic acids can be injected directly because they formed acid anhydrides in the injector by dehydration. A1 A, of o-phthalic acid and maleic acid became stable as the temperature of injector exceeded 200 C and that of succinic acid over 300 C. The coating level of stationary phase was 30% and the length of glass column was 2. 4m. Some examples by using the column were described.
