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

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.

Avantor® ACE® UltraCore SuperC18 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.

Chromolith® DIOL columns are useful as an intermediate polarity media between C18 and silica. Diol functionalised media is less polar and can have different selectivity. Chromolith® DIOL can be used with a wide range of solvents in both normal and reverse phases. In normal phase mode, the diol phase provides an alternative selectivity compared to silica whilst additionally demonstrating longer retention times that help to obtain separation. In reverse phase mode, compounds such as water-soluble vitamins, sugars or amino acids are easily baseline separated using simple mobile phases. Chromolith® DIOL columns have long lifetimes within pH range of 2,5 to 7,5, high matrix tolerance and speed of analysis.
