The video tutorial discusses chromatography, focusing on separation and column resolution based on the number of equilibria a mixture undergoes. It explains that compounds with large differences in partition ratios separate easily with fewer equilibria, while those with similar partition ratios require more equilibria. Resolution is determined by the ratio of partition ratios (alpha), which is K'2 divided by K'1. Alpha is always greater than 1 for successful separation.

Chromatographic parameters The advantage of switching to longer columns is that the theoretical plates will increase and so will the resolution. The number of theoretical plates (N) is directly proportional to the length of the column and inversely proportional to the particle diameter2.
