Unison UK-C8 is a versatile column that offers slightly shorter retention compared to ODS columns but excels in separation balance.
It features excellent acid and alkali resistance due to its unique “polymeric end-capping,” promising a long lifespan comparable to conventional ODS columns.

Advantages of this product

  • Performance count, comparable to ODS columns
  • Superior end-capping efficiency, potentially improving peak shape for basic compounds compared to ODS columns
  • Improved separation of highly polar substances with 100% aqueous mobile phases
  • Enhanced separation of isomers and related compounds
  • Excellent response for hydrophobic substances
  • Suitable for drug analysis using LC-MS

Unison UK-C8 offers performance that challenges the conventional notion that “reversed-phase separation equals ODS columns.”

Low Carryover [Optimal for LC-MS]

Unison UK-C8 demonstrates excellent low carryover performance in the LC-MS analysis of pharmaceuticals. This is attributed to a unique polymeric end-capping technique and a method of development that differs from conventional filler synthesis.
