5 Questions
What contributes to zone broadening in chromatography?
Longitudinal diffusion, resistance to mass transfer, and multiple path effect
What does the band broadening due to longitudinal diffusion depend on?
Diffusion of the solute and the flow rate of the solute through the column
When is longitudinal diffusion not very important in liquid chromatography?
At low flow rates
What does the resistance to mass transfer or mass transfer diffusion involve?
Mass transfer of solute in mobile or stationary phases
How does an increase in velocity of the mobile phase affect band broadening due to longitudinal diffusion?
It decreases band broadening as a result of longitudinal diffusion
Test your knowledge about the factors contributing to zone broadening in rate theory, including longitudinal diffusion, resistance to mass transfer, and the multiple path effect.
