Avantor® ACE® HILIC-B columns have been designed specifically for HILIC applications and are especially useful for the separation of polar analytes. These columns are part of a suit of 3 proprietary HILIC columns (HILIC-A, HILIC-B and HILIC-N) developed to enable chromatographers to achieve reproducible and successful HILIC separations using a systematic approach to method development.

Supplier: Avantor

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.

Supplier: Avantor

Really versatile general purpose apolar phase for a wide range of applications, including (for example): PCBs, simulated distillation, gases, essential oils, hydrocarbons analysis, pesticides, semivolatiles, oxygenates. HI-1 is a crossbonded phase and assure a long lifetime even under high temperature limits.

Supplier: Avantor

Background PFAS (Perfluoronated Alkyl Substances) from an LC instrument and mobile phase can interfere with the detection of PFAS in samples. The introduction of a delay column, which is plumbed before the autosampler in the LC system, will delay background PFAS to improve accuracy of PFAS measurement by LC-MS.​

Supplier: Avantor

Prevail™ HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. All phases, apart from Prevail™ Carbohydrate ES are silica-based. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes.

Supplier: Avantor

Vydac MS columns are a later development from Grace for the reversed phase HPLC separation of biomolecules. A proprietary surface treatment and bonding process give Vydac MS columns unique selectivity. A variety of reversed phases makes this product line suitable for the analysis of small peptides to large intact, undenatured proteins.
