Avantor® ACE® HILIC method development kits offer all three Avantor® ACE® proprietary HILIC phases (HILIC-A, HILIC-B and HILIC-N) in one kit. These phases offer alternative HILIC selectivity to each other, and have been developed to enable chromatographers to achieve reproducible and successful HILIC separations using a systematic approach to method development.

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.

BAKERBOND spe™ columns are disposable PP or glass columns pre-packed with high capacity sorbents contained between two 20 µm PE frits. BAKERBOND spe™ C18 PolarPlus® columns are used when BAKERBOND spe™ C18 yields low recoveries of very polar (that is water soluble) compounds.

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.

Vydac TP was the first range of wide pore media phases developed in the Vydac range and became the industry standard for peptide and protein separations. The large pores of the 300 Å TP silica give polypeptide molecules complete access to the interior of the silica pores.

Avantor® ACE® Method Development Kits (MDK) are designed to maximize selectivity, offering a powerful and reliable approach to UHPLC/HPLC method development. Based upon an ultra-inert, high efficiency silica, Avantor® ACE® phases incorporate the latest developments in LC stationary phase design, providing chromatographers with more choices for alternative selectivity, without compromising stability or robustness. A complete range of kits for all requirements is available, including porous, solid core, HILIC and bioanalytical 300 Å column kits. These kits group together the essential column chemistries for method development and are available in a wide range of column formats.

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-Amide is a uniquely designed stationary phase offering improved retention of polar compounds, enhanced phenolic resolution and alternative selectivity to C18 bonded columns. These stainless steel columns are available in a wide range of particle sizes and dimensions from capillary to preparative.

Supplier: Avantor

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.
