基于PTGC保留时间预测的气质联用系统虚拟实验室建设研究OA

This paper mainly explores the construction method and application effect of the virtual laboratory of GC-MS system.The virtual laboratory is established with reference to the physical structure of GC-MS,and is composed of virtual instrument,virtual environment,virtual workstation and so on.It can be used for qualitative and quantitative analysis of samples to be tested,and has most of the functions of GC-MS,but it has the advantages of lower cost,easier operation and supporting secondary development.The mixture samples of toluene,ethylbenzene and octanol were determined by GC-MS and GC-MS system virtual laboratory respectively.The results show that the error between measured value and simulated value can be controlled below 0.5% .The results show that the virtual laboratory designed in this paper has high precision and strong availability.
