Chromatographic animations




1. Diffusion Open
The examples explain brownian motion and diffusion



2. Principle of Chromatography Open
The  examples explain the chromatographic principle and the difference between chromatography and two-phase extraction.



3. The Purnell equation
Open
The  examples illustrate the effects of the different factors that are necessary for chromatographic resolution.



4. Band broadening
Open
The examples explain two of the effects that lead to peak broadening in chromatography, resistance to mass transfer (C term) and longitudinal diffusion (B term).



5. Golay equation
Open
The examples illustrate zone broadening in capillary columns (Golay equation) and the optimal mobile phase velocity.
