In several cases, baseline separation on the peaks may be obtained only with gradient elution and lower column loadings. Therefore, two drawbacks to elution mode chromatography, Specifically for the preparative scale, are operational complexity, as a consequence of gradient solvent pumping, and very low throughput, on account of low column loadings

hplc principle and procedure for Dummies
Yet another vital issue is the cell period pH since it can alter the hydrophobic character in the ionizable analyte. For that reason most approaches use a buffering agent, for example sodium phosphate, to control the pH. Buffers provide many uses: control of pH which influences the ionization state of the ionizable analytes, have an effect on the d
