Column care
The recommended pH range for YMC-Pack ODS-AQ is 2-7,5 in up to 100% aqueous systems and a maximum of 50 °C. Remove acid and buffer salts before storage. Store the column in methanol / water = 70/30. Clogged inlet frits often can be cleaned by changing the flow direction or replacement. For detailed information please refer to the “Column Care and Use Instructions”, which are shipped with each analytical column.
