Peak Tailing in HPLC - Crawford Scientific

Sep 18, 2017 · Peak tailing is the most common chromatographic peak shape distortion. We want to address how to go about fixing these distortions but first, let's understand what causes peak tailing. Peak tailing occurs when the peak asymmetry factor (As) is greater than 1.2 — although peaks with As greater than 1.5 are acceptable for many assays.
