用非极性固定相分离不同极性化合物时色谱峰峰形的EMG参数及计算机拟合

EMG PARAMETERS OF THE CHROMATOGRAPHIC PEAK FORM OF THE COMPOUNDS WITH DIFFERENT POLARITY WHEN SEPARATED WITH THE NON-POLAR STATIONARY PHASE AND THE COMPUTER SIMULATION

对用非极性固定相分离不同极性的化合物时色谱峰的峰形与保留值的关系进行了研究。使用非极性固定相分离不同极性的化合物时 ,不同极性化合物的色谱峰的EMG参数σ、τ与组分的保留值不存在线性关系。建立了使用非极性固定相分离极性化合物时色谱峰峰形的计算机模拟方法。该法作为《开放式气相色谱仿真软件》中的模拟方法之一 ,效果较好。

The relationship between the chromatographic peak form of the compounds with different polarity and the retain value has been studied by using non-polar stationary phase. The EMG peak parameters σ and τ are not linear with the retain value for compounds with different polarity. The simulation method has been set up which was one of the simulating method for software of Open Gas Chromatographic Emulation with satisfactory results.
