Supplier: Avantor

Avantor® Hichrom Anion/S columns are based on 10 µm silica with quaternary ammonium ion-exchange groups. These columns are optimised for non-suppressed conductivity detection and are best suited for routine separations of chloride, bromide, nitrate and sulphate.

Supplier: Avantor

Avantor® Hichrom Organic Acid columns are ion exclusion columns packed with sulphonated polystyrene-divinylbenzene.

Supplier: Avantor

These Avantor® Hichrom C8 columns offer high performance in order to tackle the most challenging reversed-phase applications. The use of ultra pure silica, advanced bonding technology, superior column specification and comprehensive batch validation all contribute to the columns’ excellent reproducibility.

Supplier: Avantor

Saturation columns are placed between the pump and the injector and they saturate the mobile phase with silica, minimising dissolution of the analytical column when working above pH 7.

Supplier: Avantor

These Avantor® Hichrom C18 columns offer high performance in order to tackle the most challenging reversed-phase applications. The use of ultra pure silica, advanced bonding technology, superior column specification and comprehensive batch validation all contribute to the columns’ excellent reproducibility.

Supplier: Avantor

This column consists of a highly efficient sulphonated polystyrene resin supplied in the calcium form. It provides excellent separations using only water as the mobile phase.

Supplier: Avantor

Avantor® Hichrom RPB is a high purity base deactivated silica which offers a unique selectivity due to the proprietary C8/C18 multi-alkyl bonding and exhaustive endcapping employed. The range includes 3,5, 5 and 10 μm phases, which are suitable for LC-MS applications and preparative separations respectively.
