| Washing method | 1. Remove buffer, salts and/or acid from column: wash for 10-15 min. using the mobile phase last used, without buffer, salts or acid. For example, if your mobile phase was 50:50 acetonitrile/20 mmol/l phosphate buffer, wash with 50:50 acetonitrile/water. 2. Remove adsorbed compounds and fix unstable baselines: Wash with 50:50 acetonitrile/water. |
||||
| Storage conditions | Remove buffer, salts and/or acid from column: wash for 10-15 min. using the mobile phase last used, without buffer, salts or acid. Then, replace the solvent with 90:10 acetonitrile/water. Tightly plug the column, and store in a cool and dry place. |

| Usable pH range | pH2～pH7.5 | ||||
| Max. pressure | 20MPa | 15MPa | |||
| Temperature range | The maximum usable temperature is 60°C. However. for regular use, please use at a constant temperature between 20°C and 50°C. | ||||
| Usable solvents | - Acetonitrile/water mobile phases are recommended. | ||||
| Other instructions | - Buffer concentration is usually sufficient at 0.005 - 0.02 mol/L. - Always filter mobile phases using a 0.5 µm or finer filter before use. - Methanol is not recommended as a mobile phase. - If using a buffer or acid, we recommend using the column only for that mobile phase. Buffers may affect performance even after washing the column. - Neutral pH will maximize retention time. |
