Halogen Exchange Reaction Products

COSMOSIL PBB-R strongly retains iodine atom which has a large dispersion force, than bromine atom. So it can separate halogen exchange reaction products that are difficult to analyze with C₁₈ column.

Surfactant Agent

C₁₈ column can not separate Triton X-100 mixturem, because (-OCH₂CH₂-) group has little hydrophobicity. However, COSMOSIL PBB-R can separate them because it distinguishes difference in the dispersion force, which depends on its molecular weight.
