Webconcept and can be calculated using Equation 4. A capillary column/any chromatography column does not contain anything resembling physical distillation plates or other similar features. Theoretical plate numbers are indirect measure of peak width for a peak at a specific retention time. WebColumn efficiency is expressed as the number of theoretical plates per meter chromatography bed (N) or as H (height equivalent to a theoretical plate, HETP), which is the bed length (L) divided by the plate number. Column efficiency is related to the band broadening that can occur on a column and can be calculated from the expression:
