The Avantor® ACE® C18-AR phase utilises a specially developed ligand combining a C18 chain with integral phenyl functionality, thus combining the benefits of both C18 and phenyl characteristics into a single phase. This can be used for ‘standard’ C18 column separations, but is additionally recommended for separations that involve compounds containing aromatic functionality.

Avantor® ACE® CN-ES combines CN polar selectivity with enhanced hydrophobicity, enabling the benefits of both interactions to be fully exploited. Extra phase stability and increased column lifetime is provided by an extended alkyl chain spacer between the silica surface and cyano group. Avantor® ACE® CN-ES is suitable for both reversed phase and normal phase separations.

Avantor® ACE® Excel® C18-PFP phase utilizes a specially developed ligand combining a C18 chain with integral PFP functionality. This results in a phase that maintains the hydrophobic, stability and low bleed characteristics of leading C18 phases, yet provides the multiple retention mechanisms of a PFP phase.

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.

Using proprietary bonding technology, the straight chain C18 hydrocarbon is bonded directly to the TYPE-C silica-hydride surface at two separate points of attachment with direct siliconcarbon bonds. This Si-C bond is virtually indestructible and confers great stability and longevity to these columns.

PRP-1 polymeric HPLC columns are designed for broad ranging uses, similar to C8 or C18 HPLC materials. They combine the best characteristics of silica-based and polymeric columns resulting in highly inert and long-lasting columns. These columns are ideal for applications that require a high degree of column to column and batch to batch consistency (quality assurance, clinical trials). Unlike C8 or C18 columns, PRP-1 has no stationary phase coating. Since there is no stationary phase to hydrolyse, the column maintains its performance characteristics longer than many C8 or C18 columns.

These useful HPLC columns have a silica hydride surface similar to other TYPE-C™ phases but the uniqueness of Diamond Hydride™ is that they have a very small amount of carbon on the surface that adjusts the hydrophobicity to a small but important level. This is an excellent choice for small, polar compounds by LCMS or HPLC.
