Excsep® Bi-phenyl column is made of ultra-high purity and ultra-high mechanical strength spherical chromatography bare silica gel, which is prepared by the unique surface modification technology and tailing technology of OneTwo Chromatography Technology. The biphenyl is bonded to the silica gel, which allows it to have both hydrophobic interaction and π electron interaction, and is suitable for the separation of aromatic rings and heterocyclic compounds.

Characteristic

1. Based on hydrophobic and π-π forces, it provides appropriate selectivity for aromatic and heterocyclic compounds.
2. It provides certain stereoselectivity, which helps to separate positional isomers.
3. Low column bleeding, compatible with universal detectors. 
4. Good batch reproducibility of fillers.
