# Seperation of Mixture Retardation Factor R Formula & Calculator

## Chromatography Retardation Factor Rf Calculation

p - Bulk density (kg/m3)
η - Porosity (%)
Kd - Distribution coefficient

Chromatography retardation factor Rf calculator - formula & step by step calculation to measure the dissolving the mixture or seperation of mixture in the fluid. R = 1 + (ρ/η) x Kd. Fluid buld density ρ in kg/m3, porosity η in percentage & distribution coefficient Kd are the key elements of this calculation.

## Formula

In environmental engineering, the below formula is used to calculate the Retardation factor Rf in the context of chromatography to seperate the mixture in the fluid or mobile phase. The step by step calculation for each set of inputs let users to understand how to perform such hazardous emission rate to air calculations manually.

In the field of environmental engineering, while working with waste management, sometimes it's important to analyse the mobile phase of a chromatographic system. The above formula & step by step calculation may useful for users to understand how the values are being used in the formula, however, when it comes to online for quick calculations, this retardation factor calculator helps the user to perform & verify such calculations as quick & easy as possible.
