Hplc tailing factor

Webionic-strength mobile phases lead to decreased peak tailing and narrower peaks for the mAb monomer. With increasing sodium chloride concentrations from 50-200 mM, the mAb peak height increases from 0.189 – 0.289. The USP tailing factor also decreases from 1.64 to 1.22. Changes are less pronounced as the http://ftp.uspbpep.com/v29240/usp29nf24s0_c621s12.html

Web27 mrt. 2024 · Peak Tailing. Tailing is basically the inverse of fronting. The peak is presented asymmetrically, with a broader second half and a narrower first half – breaking away from the ideal peak shape, with its symmetrical Gaussian profile. While the effect is similar, the circumstances of tailing are different from those of fronting. WebIn general, a HPLC system contains the following modules: a solvent reservoir, a pump, an injection valve, a column, a detector unit and a data processing unit (Fig. 1). The solvent (eluent) is delivered by the pump at high pressure and constant speed through the system. To keep the drift and noise of the detector signal as low as possible, a ...
