Chromatography Peak Resolution Calculator

Calculate resolution Rs from peak retention times and baseline widths.

In-browser processingNo account requiredPrivacy details ↗

Rs = 2 × |tR2 − tR1| / (w1 + w2)

Enter nonnegative retention times and strictly positive baseline widths in one time unit. Use baseline widths, not half-height widths. This number alone does not determine whether an experiment is adequate.

A QUICK WALKTHROUGH

How to use this tool

  1. Enter the values in one common time unit, then calculate.
  2. Enter nonnegative retention times and strictly positive baseline widths in one time unit. Use baseline widths, not half-height widths. This number alone does not determine whether an experiment is adequate.

Formula

Rs = 2 × |tR2 − tR1| / (w1 + w2)

Input basis

Enter nonnegative retention times and strictly positive baseline widths in one time unit. Use baseline widths, not half-height widths. This number alone does not determine whether an experiment is adequate.
