Avantor® ACE® UltraCore SuperPhenylHexyl solid-core (core-shell) particle columns are ideal for demanding MS work offering improved MS signal intensity and maximum MS response. These stainless steel columns combine high efficiency separations with low column back pressure. The Encapsulated Bonding Technology (EBT™) greatly increases the ligand coverage of the silica surface and effectively eliminates the effect of unbonded silanol groups on separations. This higher ligand coverage results in improved inertness, chromatographic performance and stability.

Supplier: Avantor

These high performance UHPLC columns contain high purity spherical silica.
