Hypercarb porous graphitic carbon (PGC, Hypercarb) is a unique stationary phase composed of flat sheets of hexagonally arranged carbon atoms with a satisfied valence, as in a very large polynuclear aromatic molecule, it provides extended separation capabilities, enhanced retention of polar compounds and separtion of structurally related analytes with stability at extreme pH and high temperature.

Supplier: Thermo Fisher Scientific

For fast, accurate titer analysis of monoclonal antibodies (MAbs) in harvest cell cultures. This column provides high throughput and accurate analyses through a combination of low backpressure and high efficiency. Its unique format makes automation of loading, binding, elution and collection using biocompatible systems quick and easy. A non-porous, polymeric resin with a hydrophobic divinylbenzene core and a hydrophilic surface optimised for affinity separation makes this column rugged and reproducible.

Supplier: Restek

Highly base-deactivated spherical silica manufactured by Restek. Monomeric C8 bonding. Similar to Pinnacle® DB C18, but the shorter alkyl chain provides less hydrophobic retention. Less retention can be useful for shortening analysis time, if resolution is adequate. Replaces Hypersil® BDS C8 and Pinnacle® C8 Amine.

Supplier: PerkinElmer

QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) dispersive SPE, is a leading sample preparation approach in pesticide residue analysis. It eliminates complex liquid extraction methods and extends the range of recovered pesticides. The QuEChERS procedure is fast and easy, improving laboratory productivity, resulting in fewer errors.

Pierce™ HisPur™ cobalt chromatography cartridges are convenient, ready-to-use pre-packed devices for efficient purification of polyhistidine-tagged proteins from bacterial, mammalian and baculovirus-infected cells. His-tagged proteins are purified from total soluble protein extract using a cobalt-charged tetradentate chelator immobilised onto 6% crosslinked agarose.

Supplier: Thermo Fisher Scientific

Pierce™ Glutathione chromatography cartridges are convenient, ready to use pre-packed devices for the purification of GST-fusion proteins from cellular lysates. The glutathione is immobilised through its central sulfhydryl onto 6% crosslinked agarose resin. Purification of GST-fusion proteins using glutathione (GSH) agarose beads is well documented and provides a one-step, high purity affinity purification.

Supplier: Restek

These biphenyl coulmns have a greater degree of dispersion than conventional phenyls and a greater degree of polarisability than phenyl hexyls, creating higher selectivity and a greater range of usability. With heightened interactions shows substantial increases in retention for dipolar, unsaturated, or conjugated solutes and enhanced orthogonal selectivity when using methanol mobile phases.

Supplier: Cytiva

HiLoad™ Superdex™ prep grade are prepacked XK columns designed for pre-parative gel filtration. Superdex™ prep grade is a composite matrix of dextran and highly cross-linked agarose. The steep selectivity of dextran, and the high chemical and physical stability of agarose, enable high resolution separations. The chromatography media combines high mechanical strength with high hydrophilicity, allowing high flow rates and minimal non specific interactions.

Replacement column nut, 1/16", connects capillary column to adapter

Supplier: Thermo Fisher Scientific

SilTite™ ferrules are designed for use with capillary column connectors.

Supplier: Thermo Fisher Scientific

These columns offer unique selectivity for aromatic and moderately polar analytes. Suitable for complex samples where some peaks are well resolved on a phenyl phase whilst others require a conventional alkyl phase. Based on Core Enhanced Technology, they provide fast, high resolution separations without the elevated back pressures required by sub-2 µm particles.

Supplier: VARIAN

Bond Elut™ Plexa PCX uses a polymeric cation exchange resin that combines the outstanding properties of Bond Elut™ Plexa - superior flow characteristics and improved analytical performance - with strong cation exchange functionalities. This mixed-mode SPE sorbent removes neutral and acidic interferences from the matrix, concentrates basic analytes and therefore improves sensitivity in the determination of basic compounds.

Supplier: CHIRAL TECHNOLOGIES

CHIRALPAK® QN-AX and CHIRALPAK® QD-AX are enantioselective weak anion-exchange (AX) HPLC columns. The chiral selectors for CHIRALPAK® QD-AX and CHIRALPAK® QN-AX anion exchange phases are based on complementary quinine (QN) and quinidine (QD) derivative selectors bonded to high efficiency 5 µm diameter spherical silica. The structure of these selectors is such that a tertiary amine is located in a three-dimensional cleft surrounded by additional hydrogen binding sites and a large aromatic group. This combination provides excellent separations of chiral acids.

Supplier: Thermo Fisher Scientific

HyperSep™ Retain™ PEP polymeric SPE material is a high purity, highly porous polystyrene DVB (divinyl benzene) material modified with urea functional groups to give balanced retention of polar and non polar analytes. HyperSep™ Retain™ PEP is ideal for a wide range of applications, such as drugs and metabolites in biological fluids, peptides in serum, plasma or biological fluids and environmental fluids.

Supplier: Thermo Fisher Scientific
