Descrição: Replacement tube kit

Fornecedor: Thermo Fisher Scientific

Descrição: High density, monolayer C18 reversed phase columns for very good resolution in a variety of applications.

Fornecedor: Thermo Fisher Scientific

Descrição: These sulfonamide embedded, reversed phase columns provide unique selectivity and excellent peak shape for acidic, basic, and neutral analytes. Efficient for the separations of nucleic acid and bases or pharmaceutical compounds using highly aqueous mobile phases.

Fornecedor: Thermo Fisher Scientific

Descrição: These columns are ideal for high-resolution, high efficiency analysis of monoclonal antibodies (mAbs) and associated variants. The unique non porous pellicular resin provides the resolving power to separate mAb variants that differ by as little as one charged residue.

Fornecedor: Thermo Fisher Scientific

Descrição: These columns feature a strong anion exchange resin for high resolution analysis and purification of synthetic and modified oligonucleotides.

Fornecedor: Thermo Fisher Scientific

Descrição: These columns can resolve protein isoforms that differ by a single charged residue. A thin, hydrophilic layer prevents unwanted secondary interactions. The grafted anion exchange surface provides pH based selectivity control and fast mass transfer for high efficiency separation and moderate capacity.

Fornecedor: Thermo Fisher Scientific

Descrição: These columns are used for the separation of both basic and acidic analytes, and incorporate amide-embedded polar group and multi point attachment between the ligands and the silica surface.

Fornecedor: Thermo Fisher Scientific

Descrição: These high-efficiency, silica-based columns provide excellent resolution and throughput for HPLC separations using  UV-Vis, evaporative light scattering (ELSD) or refractive index (RI) detection. The novel surface chemistry creates a unique polarity that offers significantly improved resolution for individual oligomers of ethoxylated surfactants compared with conventional C18 columns.

Fornecedor: Thermo Fisher Scientific

Descrição: These columns offer unparalleled separations of hydrophilic aliphatic and aromatic organic acids. They are compatible with 100% aqueous mobile phases and low pH conditions. They feature a patented polar-embedded stationary phase that is optimised and use-tested for hydroxyl aliphatic organic acid separations.

Fornecedor: Thermo Fisher Scientific

Descrição: The Hypersil™ green PAH columns with alkyl bonded silica and high carbon loading are suitable for the analysis of polyaromatic hydrocarbons (PAHs).

Fornecedor: Thermo Fisher Scientific

Descrição: Hypersil™ MOS and MOS-2 columns have a monolayer coverage of C8 alkyl chain chemically bonded onto the silica surface for a reproducible and efficient stationary phase. The MOS-2 is endcapped. Both C8 phases exhibit similar selectivity to ODS, but are less retentive. This can often provide reduced time for analyses, particularly for strongly hydrophobic analytes.

Fornecedor: Thermo Fisher Scientific

Descrição: Recommended for analytes with medium hydrophobicity or when a less hydrophobic phase is required to obtain optimum retention.
