The simulation of physical parameters provides a virtual environment for the design and optimization of instrumentation. applying physical laws and theorems to natural phenomena defines the behavior of analytical processes. Simulation provides means for the adjustment of specific operating parameters while maintaining the repeatability of constant parameters. The video Electric Single Particle Aerodynamic Relaxation Time Analyzer (VESPART) is an instrument that provides the diameter and charge-to-mass (q/m) ratio of particles. The simulation of the VESPART requires the modeling of the physical environment and application of modeling to simulations. Simulation includes characterization of the various natural forces that "feet particle motion within the instrument. These natural forces can be modified to determine the impact each has on particle motion. The graphical user interface is created in MS Visual Basic providing an MS Windows compatible simulating environment. The output of the simulator is a virtual, illuminated particle track similar to the actual particle track acquired by le VESPART. This paper presents the parameters of simulation as well as the output virtual particle track. Also, the benefits simulation are presented relative to research and development projects.
