This anion column line is designed to meet the special requirements of anion analysis. These four columns cover all aspects of standard anion analysis, separation of all 8 common anions in one run. The unique design of the highly cross-linked porous-packing material, and the strong covalent bonded surface chemistry, ensure excellent durability and high separation efficiency. These columns are designed to be used with carbonate-bicarbonate buffer in any concentration or with hydroxide gradient, and many other mobile phases.

Kromasil® AmyCoat and CelluCoat are new generation polysaccharide based chiral phases which stretch the limits for chiral chromatography. High purity deactivated wide pore silica is coated with tris-(3,5-dimethylphenyl) carbamoyl functionalised amylose or cellulose selector.

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™ LMS polymeric sorbent lets you elute without having to add amine modifiers, buffers, or acids. The elimination of secondary interactions means that elution of analytes can be achieved with pure organic solvents or HPLC mobile phase-compatible solvent mixtures of low ionic strength. These characteristics are crucial to allow compatibility with LC/MS or other delicate analytical techniques.

Supplier: Thermo Fisher Scientific

BioRS, strong cation exchange columns designed for 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. A hydrophilic layer surrounds the polymeric beads and eliminates hydrophobic interactions with the resin, resulting in very efficient peaks. A proprietary grafted cation-exchange surface provides pH selectivity control for high-resolution separations.

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: Thermo Fisher Scientific

Based on Core Enhanced Technology, using 4 µm solid core particles, these columns allow users of conventional HPLC methods to enjoy performance far beyond that of columns packed with 5, 4 or even 3 μm fully porous particles. Very high separation efficiencies, using standard HPLC instruments and conditions, provide increased peak resolution and lower limits of detection. An ultra-stable packed bed results in exceptionally robust columns that demonstrate excellent retention and response reproducibility.

CROWNPAK® CR(+) and CR(-) contain a chiral crown ether as a chiral selector, which is coated onto a 5 µm silica support. CROWNPAK® selectors are mainly used to separate chiral amino acids and other small molecules with primary amine groups. The elution order of the enantiomers can be reversed when necessary.

Supplier: VARIAN

The PLRP-S family of products consists of a range of pore sizes and particle sizes, all with identical chemistry and fundamental adsorptive characteristics. The particles are inherently hydrophobic so there is no bonded phase, alkyl ligand required for reversed-phase separations. This gives a highly reproducible material that is free from silanols and heavy metal ions. Within the extensive product range are columns suitable for analytical separations and preparative purifications.

Supplier: CHIRAL TECHNOLOGIES

The HPLC analytical guard cartridges need to be mounted in a cartridge holder to be connected to the analytical column. For maximum lifetime, analytical columns should be used in series with an appropriate guard cartridge or column. Both formats are available with the packing material to match the protected column.

TSK-Gel®, Guard cartridge for 2 mm I-Ø columns

Supplier: VARIAN

Bond Elut™ PH is a non-polar bonded silica material which exhibits a different selectivity to alkyl or aliphatic functionalised phases such as C8 or cyclohexyl. The electron density present in the aromatic ring affords an enhancement in the retention of conjugated or aromatic ring-containing analytes due to desirable pi-pi interactions.

Supplier: Thermo Fisher Scientific

These columns are designed for ion pairing reversed phase HPLC (IP-RPLC) analysis of aminoglycoside antibioticss, including drug purity characterisation and quantification, therapeutic drug monitoring and residual control testing in meat / poultry. The Acclaim™ AmG C18 stationary phase is based on a proprietary C18 bonding technology that provides extremely high stability towards acidic conditions.

Supplier: Thermo Fisher Scientific

Accucore™ Polar Premium is a rugged amide embedded C18 phase that offers complementary selectivity to conventional C18. Based on Core Enhanced Technology, they provide fast, high resolution separations without the elevated back pressures required by sub-2 µm particles.

PBA is a unique sorbent consisting of a phenylboronic acid covalently linked to a silica gel surface. Covalent processes result in a higher retention to the sorbent surface than other mechanisms, resulting in superior clean-up. The boronate group has a high specificity for cis-diol containing compounds such as catechols, nucleic acids, low molecular weight proteins and carbohydrates.

Supplier: VARIAN

Bond Elut™ PRS is a strong cation exchange sorbent that is also relatively high in polarity. With no appreciable degree of hydrophobicity, in non-polar solvents, PRS is capable of polar and hydrogen bonding interactions. Due to the very low pKa of PRS, a high ionic strength eluent must be used, and so the use of PRS is recommended for weaker cationic species such as pyridinium compounds.

Supplier: VARIAN

A medium polarity sorbent with many uses, Bond Elut™ CN-E is ideal for applications in which extremely non-polar compounds would be irreversibly retained on high carbon load sorbents such as C₈ and C₁₈. This endcapped version of the cyano sorbent is best utilised when extracting analytes from an aqueous matrix.

The Bond Elut™ Certify extraction cartridge utilises a packed bed consisting of a special, non-polar C8 sorbent and a strong cation exchanger (SCX). Certify is most commonly used to extract basic (cationic) drugs from urine and blood, but it is also very effective for extraction of a wide range of compounds from a diverse range of aqueous matrices.

Supplier: Thermo Fisher Scientific

The Zeba™ Desalting chromatography cartridges, 7 kDa MWCO, contain a high-performance resin for desalting or buffer exchange applications. This resin is ideal for removing low molecular weight compounds including salts, fluorescent dyes, biotin and other small labeling reagents. Zeba™ Desalting Cartridges provide fast, easy and reproducible chromatographic separations and can be regenerated for multiple uses. They efficiently process samples from 50 to 1500 µl.

Supplier: VARIAN

Bond Elut™ PSA is an alkylated amine sorbent that contains two different amino functionalities, one secondary and one primary. This gives a slightly higher pKa and ionic capacity compared to Bond Elut™ NH₂. The PSA functional group is a very effective bidentate ligand and is therefore an excellent sorbent for chelation applications. PSA has a significantly higher carbon load than most amino functional sorbents and thus is a better choice for polar compounds, which retain too strongly on Bond Elut™ NH₂.

Hexafluoroisopropanol (HFIP) is used as a solvent in GPC for the analysis of important industrial polymers such as polyesters, polyamides and polylactide/glycolide copolymers. For greatly improved performance in extremely polar solvents such as HFIP and trifluoroethanol, we have developed novel 'multipore' technology to produce PL HFIPgel, a PS/DVB packing featuring a monodisperse particle size, high pore volume and high resolution.
