How to use this tool

  1. Estimate separation resolution between two peaks using baseline widths.
  2. Set first retention time, second retention time, first baseline width, second baseline width in the indicated units.
  3. Calculate and compare peak resolution, retention separation.

Try this example

{
  "t1": 5,
  "t2": 6,
  "w1": 0.4,
  "w2": 0.6
}

Accuracy and scope

Baseline-width resolution metric for isolated peaks; no identification, purity or experimental method recommendation.
