Avantor® ACE® C18-300 columns provide great reproducibility and column lifetime. These stainless steel columns are available in a wide range of particle sizes and dimensions from capillary to preparative. These columns are designed for a wide range of chromatographic applications, to provide great performance with acidic, basic and neutral molecules. These columns provide excellent peak shape even at extremely low levels of additives such as TFA, making them ideal for LC/MS applications.

Supplier: Avantor

Solid phase extraction, as a sample preparation technique, often requires stationary phases stable in the whole pH range. Styrene-divinylbenzene (SDB) copolymer sorbent can improve the quality of sample preparation.

Supplier: Avantor

These SPE columns are designed for the extraction of pesticides from water.

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

These columns with high purity base deactivated porous silica are ideal for the separation of basic molecules.

Supplier: Avantor

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® Alltima HP Cyano HPLC columns are high quality phases designed for general purpose applications.

Supplier: Avantor

Avantor® Apollo HPLC columns use high purity, base deactivated silica for powerful separations.

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

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.
