pH range -
Eluent: 0 - 12 Sample: 0 - 14
Regeneration -
Note: Ensure that the maximum pressure is never exceeded during regeneration. If the pressure becomes too high, reduce the flow rate. Regeneration: Disconnect the column outlet from the downstream functional units such as suppressor or detector. Instead, collect the flow of liquid in a beaker. Rinse the column with ultrapure water before and after regeneration. Depending on the type of contamination, proceed in accordance with one of the following instructions: Organic contamination: Regenerate the column in the opposite direction to the flow at 1 mL/min with the following solutions in succession: 1 h with ultrapure water 1 h with acetonitrile-water mixture (40:60) 1 h with ultrapure water Inorganic contamination: Regenerate the column in the opposite direction to the flow at a flow rate of 1 mL/min over 1 h with 50 mmol/L nitric acid .
