High speed and high resolution! Achieving retention of polar substances and improvement of peak shape.
"Polaris" is a column designed for LC/MS with a mobile phase that achieves high speed and high separation efficiency. The packing material is based on high-purity silica, with alkyl chains and polar modification groups bonded to it. As a result, the surface of the polar-modified packing material is easily wetted by polar solvents, exhibiting unique selectivity. [Features] ■ Good retention for polar compounds that tend to elute in the void volume ■ Maintains good peak shape due to the mild characteristics of polar interactions ■ The polar modification groups play a role in inactivating the basic sites on the silica surface ■ Reduces interactions between silanol and basic substances ■ Exhibits completely different selectivity compared to conventional C18 packing materials *For more details, please refer to the related links or feel free to contact us.

【Other Features】 ■Improvement of Separation Ability and Reproducibility - Standard reverse phase columns, particularly C18 columns, often exhibit the so-called "sleeping phenomenon" when used with mobile phases that have a high ratio of water. - Functional groups with polar modifying groups tend to extend even under conditions with a high water ratio, increasing the interaction between the analyte and the functional groups. - Polaris shows high resistance to the sleeping phenomenon, resulting in improved separation ability and reproducibility. *For more details, please refer to the related links or feel free to contact us.
