WebTailing factor (T) In practice, perfectly symmetric peaks are very rare. In a chromatogram they often show some degree of tailing. Peak tailing is measured by the tailing factor T. This factor describes the peak asymmetry, i.e. to which extent the shape is approximated to the perfectly symmetric Gaussian curve. The tailing factor is mea - Web23 Jun 2024 · Within asymmetric peaks, there are two possibilities that could exist; Fronting and Tailing. If a peak has a wider front half (distance A) compared to the back half (distance B), it called “fronting” (or “leading”) and vice versa is known as “tailing”.
