[3]Troubleshooting HPLC- Tailing Peaks - Restek
WebI need tail factor and resolution values. So I tried to drag 'Tail Factor' and 'Resolution USP' under 'Peak' into report. The names showed up, but the values did not. Then I found the Extended Performance Report including those two values, I tried a second time. The values did not show up neither (shown in the picture attached below). WebSymmetry factor (S, also called "tailing factor") is a coefficient that shows the degree of peak symmetry. It is represented in equation (5) based on the measurements shown in Fig. 2. S>1: Tailing peak. S=1: Peak with Gaussian distribution (symmetry) S<1: Leading peak. Caution is required since both the theoretical plate number and symmetry ...
