Technical Data
Porosity and Molecular Weight Range
MZ-Gel SDplus consists of a cross-linked copolymer styrene divinylbenzene with a very narrow pore and particle size distribution. Our GPC columns are available in 7 porosities and linear as new and in refill. Typical plate count for the material MZ-Gel SDplus 3µm is > 100,000 plates/m. The 5µm material also has a high selectivity and typically achieves 80,000 - 100,000 theoretical plates/m.
| Porosity | Molecular weight range | Exclusion limit |
| 50Å | < 2.000 | 3.000 |
| 100Å | < 3.000 | 5.000 |
| 500Å | < 20.000 | 20.000 |
| 10e3 Å | 1.000 - 40.000 | 70.000 |
| 10e4 Å | 4.000 - 500.000 | 700.000 |
| 10e5 Å | 10.000 - 2.000.000 | 4.000.000 |
| 10e6 Å | 200.000 - 10.000.000 | > 10.000.000 |
| Linear | 1.000 - 1.000.000 | > 2.000.000 |
Solvent compatibility
MZ-Gel SDplus GPC columns are manufactured, tested and shipped in THF as standard. Of course, they are also available in other common solvents on request. When changing the solvent, the swelling behaviour must be taken into account.
GPC solvents can be divided into four groups from very strong to weak according to their swelling behaviour. This results in the conversion options shown on the pictureC
Do you need your GPC columns in THF, DMF, DMSO, or Chloroform? Specify your required solvent when ordering, and we will ship your GPC column set ready for use.
Are you looking for GPC columns suitable for light scattering detection (multiangle light scattering - MALS)? Our MZ-Gel SDplus LS GPC columns are specially treated to prevent bleeding. Ask for your customized offer with suitable columns for your analytical question.
