查询词典 flying column

The optimum condition for separating and purifying SAM was using the solution at pH of 5.0 containing 3.0 g SAM per liter at the flow velocity of 6 L/h through the ion-exchange column (φ50 mm×1500 mm)filled with D152 resin. Impurities were removed first by eluting the column with double-distilled water and acetic acid, and then with 9 L to 15 L of sulfuric acid of 50 mmol/L concentration at the flow velocity of 6 L/h.
