WebDec 1, 2024 · Note if you are using the previous USP method, the updated USP states that a range of only 5 times the half-height peak width is permitted when the chromatography does not allow the wider range. Scope This article applies to versions 2.2 through 2.7 of OpenLab CDS. References WebUSP tailing factor T. A tailing peak has a front of greater than 1.0, while a fronting peak has a front of less than 1.0.
