对色谱分析过程的理论研究和实验,运用Actionscript程序建立了场景式实时交互气相色谱网络化虚拟仪器与虚拟实验室,根据色谱柱效与载气流速及柱温之间的关系．以醇系物考察对象构建了不同分析条件下保留参数的预测模型,并椐此模型优化了程序设计。在所建立的气相色谱网络虚拟仪器上,可动态实时绘制出不同操作条件下的色谱流出曲线,并可通过动态实时交互来改变载气流速、分离柱温度、进样量及试样组成等参数,模拟获得最佳流速、理论塔板高度及定量计算等虚拟实验结果,并列表给出了各种模拟计算与实验值问的对比结果。所开发的网络虚拟色谱仪具有逼真的场景,可按真实仪器操作过程进行各种模拟操作,对于仪器的操作培训、色谱实验的网络学习具有较大的应用价值。
Based on the theoretical research and experiment of chromatographic analysis, a scene-based real-time interactive GC-based virtual instrument and virtual laboratory were established using Actionscript program. The relationship between chromatographic efficiency and carrier gas flow rate and column temperature was established. The prediction models of retention parameters under different analysis conditions were constructed based on the investigated objects of alcohol series. The model was optimized for programming. On the established GC virtual instrument, the chromatographic outflow curve under different operating conditions can be dynamically drawn in real time, and the parameters such as carrier gas flow rate, separation column temperature, injection volume and sample composition can be changed through dynamic real-time interaction , Simulation of the optimal flow rate, the theoretical plate height and quantitative calculations and other virtual experimental results, and the list gives a variety of simulation calculations and experimental results of the comparison results. The developed network virtual chromatograph has the realistic scene, can carry on the various simulation operations according to the real instrument operation process, has the great application value to the instrument operation training, the chromatographic experiment network study.
