摘要
合成了2,5-二甲基-3,4-二苯基苯基接枝聚硅氧烷气相色谱固定相,接枝量分别为10%、20%、30%,静态法涂柱,评价了其色谱性能。该类固定相柱效高、使用温度范围宽、热稳定性好,适用于芳烃混合物、苯类取代物、稠环芳烃化合物的分离分析。
The 2,5-dimethyl-3,4-diphenyl-phenyl polysiloxane was synthesized and used as stationary phase for capillary gas chromatography（GC）,the content of 2,5-dimethyl-3,4-diphenyl-phenyl group were 10%,20% and 30% that coated capillary columns by static method.The chromatography performance of these columns were evaluated,the new stationary phase showed high column efficiency,thermal stability up to 350 ℃.The substituted benzene and polycyclic aromatic mixtures can be separated well on these columns.
