Separation Properties of PFP
COSMOSIL PFP uses dipole-dipole and π-πinteractions. It offers strong retention for compounds with strong dipole moments, e.g. cationic or halogenated compounds. It also has high steric selectivity for structural isomer separations.

Usage Information

|---|---|---|---|---|---|---|
| I.D. (mm) | 2.0 | 3.0 | 4.6 | 10.0 | 20.0 | 28.0 |
| 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 methanol/20 mmol/l phosphate buffer, wash with 50:50 methanol/water. 2. (If you used a buffer, always do step 1 first!) Remove adsorbed compounds and fix unstable baselines by washing with methanol and/or THF. |
|||||
| Storage conditions | Short-term (up to a week): 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 methanol/20 mmol/l phosphate buffer, wash with 50:50 methanol/water. Long-term: 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 70% methanol or acetonitrile : 30% water. In either case, 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℃. However. for regular use, please use at a constant temperature between 20°C and 50°C. | |||||
| Usable solvents | Any solvent that will not dissolve the silica gel (such as alkaline solutions) or cleave the stationary phase (such as very acidic solutions) is usable. Note: For solvents with high viscosity, please watch the system pressure and keep it below 20 MPa. Also, please wash the column after using acidic mobile phases or solvents with high freezing points. |
|||||
| 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. - Acetonitrile is not recommended as a mobile phase. |
