The is a specialized tool (available as online web apps, Excel spreadsheets, or embedded in chromatography data systems) designed to predict the geometrical and operational parameters needed to make two different columns produce equivalent chromatographic results . The Core Principle: Geometric Scaling The calculator is not a black box; it is built on well-established chromatographic theory. The fundamental premise is that to maintain the same separation quality (resolution, relative retention order), the linear mobile phase velocity and the ratio of column length to particle size must be preserved.
[ \frac{L_1}{d_{p1}} = \frac{L_2}{d_{p2}} ] hplc column equivalent calculator
The key equation for column equivalence is: The is a specialized tool (available as online
