Chromatography columns separate molecules within mixtures during gas or liquid chromatography. Filled with stationary phase compositions or chemical compounds, the prepacked options reduce the preparing time required. The vertical pieces are able to withstand extreme temperatures and pressure fluctuations experienced when the mobile phase is forced through the medium. Meet preparative and analytical laboratory procedures with the chromatography columns to separate dissimilar moving components based on individual solvent polarity, composition, and size. The right chromatography control system allows to automate the delivery of cleaning, sanitizing and conditioning buffers to the packed column, and can enable to cycle the chromatography column several times during the batch, requiring smaller columns and subsequent lower capital investment.

Código de Artigo: (24152.)
Fornecedor: Merck
Descrição: This column with bonded poly(ethylene glycol) phase allows highly reproducible analyses of fatty acid methyl esters (FAMEs), specifically the omega 3 and omega 6 fatty acids. It is tested to ensure reproducible FAME equivalent chain length (ECL) values and resolution of key components.
UOM: 1 * 1 unid.


Fornecedor: Avantor
Descrição: * Use with freestanding holder HI-161 and column coupler HI-081, please see “HPLC Guard Column Holders and Accessories”.

Fornecedor: Avantor
Descrição: 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.

Fornecedor: Avantor
Descrição: Avantor® ACE® C18-PFP phase utilises 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.

Fornecedor: Avantor
Descrição: 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.

Fornecedor: Avantor
Descrição: Avantor® ACE® C18 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.
