WebEfficiency testing is the analysis of the residence time distribution for a tracer substance passing through the column. Typical test signals applied to the column are pulse or … WebColumn efficiency is typically defined in terms of two parameters (Fig 4): • Peak broadening over the column is described by an equivalent number of theoretical plates • Peak symmetry is described by a peak asymmetry factor, A s The procedure is described in each Cytiva resin protocol and is also described in this Column efficiency testing ...
