|
| Features
|
|
dihydroxypropyl modified silica for RP and NP chromatography
less polar than unmodified silica, very easily wettable with water
available pore sizes 100, 300, 500, 1000 and 4000 Å, available particle sizes 5 µm and 7 µm
separation mechanism based on polar interactions (hydrogen bonds)
pH stability at 20 °C: 2 – 8
Please note! Eluent in column is n-heptane. When using an eluent which is not miscible with n-heptane (e. g. water), it is necessary to rinse the column with THF first.
