MZ-Gel SDplus
Especially for organic eluents
MZ-Gel SDplus is a high-performance copolymer styrene divinylbenzene with a high degree of cross-linking developed by MZ-Analysentechnik GmbH. It was specially developed for demanding and high-performance GPC. We produce our MZ-Gel SDplus in compliance with high quality requirements and test each individual column in quality control.
- Absolutely spherical particle shape with very narrow particle and pore size distribution
- Available in newly developed state-of-the-art column hardware with guaranteed refill option
- Particularly reliable and long-term stable
Long-term stability and reproducibility: MZ-Gel SDplus - new and after >1,000 injections.
Technical Data
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.

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 following conversion options:
