Slings should have a minimum design factor appropriate to the type of material as specified in the appropriate section. … Web1 Sep 2014 · This is illustrated with Figure 4, where Figure 4a has Rs = 1.5 and both peaks are symmetric, so the tailing factor (TF) is 1.0. In Figure 4b, the peaks have the same retention times, but the first peak has TF = 1.5. My measurements show a valley height of 19%, so for a 1:1 peak height ratio this equates to Rs ≈ 1.1.

Web8 Nov 2024 · The tailing factor ( T) is based on the measurement of the half-width parameters a and b at 5% of the peak height, and is calculated as (4) T= a+b 2a The factor T is very close to the asymmetry factor when the tailing is moderate. The relationship between the asymmetry factor and the USP tailing factor depends on the peak shape.
Web1 Sep 2014 · The asymmetry factor, A, is defined as. A= y / x. The Tailing Factor is defined by the USP as the distance from the front edge of the peak to the back edge, divided by the distance from the front edge to the centreline, with all distances measured at 5% of the maximum peak height (Figure 2).
