Peak Resolution in Chromatography Solution

STEP 0: Pre-Calculation Summary

Formula Used

Peak Resolution = (Retention Volume of Molecule 2-Retention Volume of Molecule 1)/((Width of Chromatographic Peak of Molecule 1+Widths of Chromatographic Peak of Molecule 2)/2)
R_s = (V_R2-V_R1)/((W_b1+W_b2)/2)
This formula uses 5 Variables

Variables Used

Peak Resolution - Peak Resolution is the difference in retention times between the two peaks, divided by the combined widths of the elution peaks.
Retention Volume of Molecule 2 - (Measured in Cubic Meter) - Retention Volume of Molecule 2 is the volume that has passed through the column since the target molecule 2 was introduced onto the column.
Retention Volume of Molecule 1 - (Measured in Cubic Meter) - Retention Volume of Molecule 1 is the volume that has passed through the column since the target molecule 1 was introduced onto the column.
Width of Chromatographic Peak of Molecule 1 - (Measured in Meter) - Width of Chromatographic Peak of Molecule 1 is the distance between points of molecule 1 where lines tangent to the peak's left and right inflection points intersect the baseline.
Widths of Chromatographic Peak of Molecule 2 - (Measured in Meter) - Widths of Chromatographic Peak of Molecule 2 is the distance between points of molecule 2 where lines tangent to the peak's left and right inflection points intersect the baseline.

STEP 1: Convert Input(s) to Base Unit

Retention Volume of Molecule 2: 10.5 Milliliter --> 1.05E-05 Cubic Meter (Check conversion here)
Retention Volume of Molecule 1: 9.56 Milliliter --> 9.56E-06 Cubic Meter (Check conversion here)
Width of Chromatographic Peak of Molecule 1: 30 Millimeter --> 0.03 Meter (Check conversion here)
Widths of Chromatographic Peak of Molecule 2: 27 Millimeter --> 0.027 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_s = (V_R2-V_R1)/((W_b1+W_b2)/2) --> (1.05E-05-9.56E-06)/((0.03+0.027)/2)

Evaluating ... ...

R_s = 3.29824561403509E-05

STEP 3: Convert Result to Output's Unit

3.29824561403509E-05 --> No Conversion Required

FINAL ANSWER

3.29824561403509E-05 ≈ 3.3E-5 <-- Peak Resolution

What is Column Chromatography?

Column chromatography separates substances based on differential adsorption of compounds to the adsorbent as the compounds move through the column at different rates which allow them to get separated in fractions. This technique can be used on a small scale as well as large scale to purify materials that can be used in future experiments. This method is a type of adsorption chromatography technique.

How to Calculate Peak Resolution in Chromatography?
