Web30 okt. 2024 · Furthermore, a higher return loss value signifies less reflection in the wires. A better VSWR value results in a higher return loss, and if the VSWR degrades, then the return loss decreases as well. For this reason, we desire a loss in this instance, and a high return loss is preferable. Web16 sep. 2024 · Retention/retardation factor (Rf) can be calculated by the relative migration values of solute (analyte) and the solvent front. Rf = Migration of analyte / Migration of solvent front.
