Webb13 sep. 2024 · Using Column Efficiency to Optimize Resolution. A third approach to improving resolution is to adjust the column’s efficiency by increasing the number of theoretical plates, N.If we have values for k B and \(\alpha\), then we can use Equation \ref{12.3} to calculate the number of theoretical plates for any resolution. Table 12.3.1 … Webb11 sep. 2024 · They described column efficiency in terms of the number of theoretical plates, N, \[N=\frac{L}{H} \label{12.10}\] where L is the column’s length and H is the height of a theoretical plate. For any given column, the column efficiency improves—and chromatographic peaks become narrower—when there are more theoretical plates.
