Unformatted text preview: n packing. i) Longitudinal diffusion is a source of band broadening in a column in which an analyte diffuses from the concentration center of a band to the more dilute regions on either side. j) Eddy diffusion is a source of band broadening in a column in which analyte particles travel through the column by pathways that differ in length, and hence time. k) The resolution (Rs) of a column for two analytes (A eluting before B) is given by Rs = [tR(B) - tR(A)]/[(WA + WB)/2], where W is the baseline width of a chromatographic peak in the same units as the analyte retention t...
