If the dif...Using the chromatogram shown below, calculate the retention factor for each peak 1-4 and find the resolution and relative retention for each pair of adjacent compounds. (Hint: use a ruler!) If the difference between the retention times remains the same, how would the peak widths have to change? Calculate the number of theoretical plates for each compound and the average number of theoretical plates for the column.

The distillate of a simple distillation is always enriched in the lower boiling compound.Every vaporization-condensation event (called a "theoretical plate") is similar to a simple distillation, and each event enriches the distillate in the lower boiling component.

The dot represents a molecule that has just left the stationary phase is about to diffuse across the mobile phase and re-encounter the stationary phase on the other side of the column.
