WebHPLC column separations can often exploit multiple differences in the molecular properties of the target molecules. Generally, the structure and chemistry of the HPLC column packing (stationary phase) determines the analyte elution profile. HPLC column sizes range from capillary to process scale. WebThere are a couple of rules of thumb to follow: #1. For best results, use a buffer that has a pH at least 2 units away from the pKa for the analyte of interest. If the pH of the mobile phase is too close to the analyte’s pKa, you might observe split peaks or shoulders. If your analyte is acidic, then selecting a pH below its pKa results in ...
