Fda tailing factor
WebJul 28, 2024 · Tailing factor (also called symmetry factor A S): Peak tailing is a notorious phenomenon and can affect the accuracy estimation of a chromatographic system as peak integration based on where the peak ends could be very challenging. It is essential to determine the location of the upslope and downslope, failing which the accuracy may drop. WebThe tailing factor is determined by drawing a perpendicular line from the peak centre to the baseline of the peak. Then the peak width and the front half-width are measured for the peak at 5% of the height of the peak. …
