MZ-Gel SDplus LS linear 5µm 40x4,6mm SEC / GPC Guard Columns

The MZ-Gel SDplus LS linearÅ pre-columns 50x8.0mm, 5µm are used to protect MZ-Gel SDplus LS linearÅ columns with an inner diameter of 8.0mm. These precolumns are ready-to-use hardware and do not require a holder. Installation can be performed either with the AP5101 column coupler or using a short piece of capillary tubing. We recommend selecting the same pore size for the precolumn as the smallest pore size in the main column series.

Features and Benefits

• Highly cross-linked polystyrene-divinylbenzene polymer (manufactured in Mainz, Germany)
• Narrow pore and particle size distribution
• Available in common organic solvents, e.g., THF, DMF, chloroform, acetone
• Available with titanium frits
• High separation efficiency for oligomers, epoxides, and polymer additives
• Specifically optimized for light-scattering detectors
• Compatible with conventional HPLC systems

Additional Information

The MZ-Gel SDplus LS series consists of a highly cross-linked polystyrene-divinylbenzene polymer designed for organic size-exclusion chromatography (SEC) or gel permeation chromatography (GPC). Thanks to a special post-treatment process, this series exhibits extremely low phase bleeding, making it ideal for light scattering detection (LS, MALS). Compatibility with many organic solvents in addition to THF, such as DMF, chloroform, and acetone, allows for the analysis of a wide variety of polymers. The service life can be extended by using appropriate pre-columns.
