Bandspreading
The dilution of the chromatographic band as it moves down the column. The peak is injected as a slug, and, if not for the process of band broadening, each separated component would elute as a narrow slug of pure compound. The measure of band broadening is band width, tw, or more correctly, the number of theoretical plates in the column, N.
Al this stuff I have already read not once. But what about the band dilution mechanisms? Do they exist in the Mother Nature? What about inclusion and association modes of dilution? No one reports!
