Analyzing Polymers of Very High Molecular Weight
• Optimized design for polyolefin analysis • High temperature capability • High resolution with no damage from sample shear provides clean separations PLgel Olexis is designed for the analysis of very high molecular weight polymers, specifically polyolefins. The column resolves up to 100,000,000 g/mol (polystyrene in THF), and is packed with 13 µm particles to optimize efficiency and resolution without the risk of sample shear degradation during analysis. The packing of PLgel Olexis has the mechanical stability and robustness expected from a PLgel column, and so it is able to operate up to 220 °C for the analysis of highly crystalline materials. Tip Remember to heat and cool columns for high temperature analysis slowly to avoid damage from thermal shock.
