These Ultra biphenyl columns are made of high-purity, type-B silica that minimises activity and creates high-density bonding. These columns are designed for selective and reliable HPLC applications.
- Substantial increases in retention, especially for dipolar, unsaturated, or conjugated solutes
- Enhanced orthogonal selectivity when using methanol mobile phases
- Ideal for increasing sensitivity and selectivity in LC-MS analyses
These columns provide a greater degree of dispersion than conventional phenyls and a greater degree of polarisability than phenyl hexyls, creating higher selectivity and a greater range of usability.
