Capacity Factor Formula:
From: | To: |
Definition: This calculator determines the capacity factor of solute 2 based on relative retention and the capacity factor of solute 1.
Purpose: It helps in chromatographic analysis to understand the retention behavior of different solutes.
The calculator uses the formula:
Where:
Explanation: The capacity factor of solute 2 is calculated by multiplying the relative retention by the capacity factor of solute 1.
Details: Capacity factors are crucial in chromatography for understanding solute retention and separation efficiency.
Tips: Enter the relative retention (α) and capacity factor of solute 1 (k₁'). All values must be > 0.
Q1: What is relative retention (α)?
A: Relative retention is the ratio of adjusted retention times for two components in chromatography.
Q2: What does the capacity factor indicate?
A: The capacity factor measures how long a solute is retained by the stationary phase relative to the mobile phase.
Q3: What's a typical range for capacity factors?
A: Ideal capacity factors typically range between 1 and 10 for good separation in chromatography.
Q4: How is relative retention related to selectivity?
A: Relative retention is a measure of chromatographic selectivity between two components.
Q5: Can this calculator be used for HPLC?
A: Yes, the same principles apply to HPLC, GC, and other chromatographic techniques.
