Simulations based on the mathematical models outlined in Part 1 are used to study the dependence of peak broadening on design and performance parameters as well as on the diffusion coefficient of the analyte particles (e.g., ions, molecules), the viscosity of the carrier solution and the temperature of the flow. The Peclet numbers of the various sections of the flow system are calculated by the equations discussed in Part 1. The predictions from the simulations agree fairly well with earlier experimental data. On the basis of the results obtained, various possibilities for increasing the sample frequency of single-line flow-injection systems are outlined.
