1. What is Capacity Factor of Solute 2?

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.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( k_2' \) — Capacity factor of solute 2
• \( \alpha \) — Relative retention
• \( k_1' \) — Capacity factor of solute 1

Explanation: The capacity factor of solute 2 is calculated by multiplying the relative retention by the capacity factor of solute 1.

3. Importance of Capacity Factor Calculation

Details: Capacity factors are crucial in chromatography for understanding solute retention and separation efficiency.

4. Using the Calculator

Tips: Enter the relative retention (α) and capacity factor of solute 1 (k₁'). All values must be > 0.

5. Frequently Asked Questions (FAQ)

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.
