Web1 jul. 2012 · A buffer concentration of 5–10 mM usually is adequate to buffer the mobile phase, column, and injection solvent in reversed-phase separations. If buffer concentration problems are suspected, double the concentration and see if this fixes the peak shape. After the mobile phase is eliminated as the problem source, look to the column. WebIf you want to reverse-flush, just reconfigure the column. Simply reverse the column and flush to waste. Disconnect the detector, because you don’t want to flush any particles into the detector cell. By reading the full article, you will learn the significance of back flushing of an HPLC column.
