Relative Retention given Adjusted Retention Times Solution

STEP 0: Pre-Calculation Summary
Formula Used
Actual Relative Retention = (Adjusted Retention Time of Solute 2/Adjusted Retention Time of Solute 1)
αR = (tr2'/tr1')
This formula uses 3 Variables
Variables Used
Actual Relative Retention - Actual Relative Retention is the ratio of adjusted retention times for any two components.
Adjusted Retention Time of Solute 2 - (Measured in Second) - The Adjusted Retention Time of Solute 2 is the removal of time taken by the mobile phase to travel the column from the retention time of solute 2.
Adjusted Retention Time of Solute 1 - (Measured in Second) - The Adjusted Retention Time of Solute 1 is the removal of time taken by the mobile phase to travel the column from the retention time of solute 1.
STEP 1: Convert Input(s) to Base Unit
Adjusted Retention Time of Solute 2: 10 Second --> 10 Second No Conversion Required
Adjusted Retention Time of Solute 1: 5 Second --> 5 Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
αR = (tr2'/tr1') --> (10/5)
Evaluating ... ...
αR = 2
STEP 3: Convert Result to Output's Unit
2 --> No Conversion Required
FINAL ANSWER
2 <-- Actual Relative Retention

What is Chromatography?

A separation process based on the various partitioning coefficients of different solutes between the two phases.
Involving the interaction of solute(s) and two phases
Mobile phase: A gas or liquid that moves through the column.
Stationary phase: A solid or liquid that remains in place.

What are the types of Chromatography?

1) Adsorption chromatography
2) Ion-exchange chromatography
3) Partition chromatography
4) Molecular Size exclusion chromatography
5) Affinity chromatography

FAQ

What is Relative Retention given Adjusted Retention Times?
The Relative retention given adjusted retention times formula is defined as the ratio of adjusted retention times for any two components. The greater the relative retention, the greater the separation and is represented as αR = (tr2'/tr1') or Actual Relative Retention = (Adjusted Retention Time of Solute 2/Adjusted Retention Time of Solute 1). The Adjusted Retention Time of Solute 2 is the removal of time taken by the mobile phase to travel the column from the retention time of solute 2 & The Adjusted Retention Time of Solute 1 is the removal of time taken by the mobile phase to travel the column from the retention time of solute 1.
How to calculate Relative Retention given Adjusted Retention Times?
The Relative retention given adjusted retention times formula is defined as the ratio of adjusted retention times for any two components. The greater the relative retention, the greater the separation is calculated using Actual Relative Retention = (Adjusted Retention Time of Solute 2/Adjusted Retention Time of Solute 1). To calculate Relative Retention given Adjusted Retention Times, you need Adjusted Retention Time of Solute 2 (tr2') & Adjusted Retention Time of Solute 1 (tr1'). With our tool, you need to enter the respective value for Adjusted Retention Time of Solute 2 & Adjusted Retention Time of Solute 1 and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Actual Relative Retention?
In this formula, Actual Relative Retention uses Adjusted Retention Time of Solute 2 & Adjusted Retention Time of Solute 1. We can use 3 other way(s) to calculate the same, which is/are as follows -
  • Actual Relative Retention = (Capacity Factor of Solute 2/Capacity Factor of Solute 1)
  • Actual Relative Retention = (Partition Coefficient of Solute 2/Partition Coefficient of Solute 1)
  • Actual Relative Retention = (Capacity Factor of Solute 2/Capacity Factor of Solute 1)
