WebPeak Tailing In the real world of practical chromatography, perfectly symmetric peaks, as in Figure 1(a), are very rare. More common are peaks that show some degree of tailing. Peak tailing is often measured by the peak asymmetry factor (A s): where a is the width of the front half of the peak, and b is the width of the back
