The AquaSil™ C18 columns provide a versatile C18 phase for a wide range of applications. Combining a C18 phase with a hydrophilic end-capping, AquaSil™ C18 columns offer a unique material for reversed phase chromatography, offering alternative selectivity, up to twice the retention for polar compounds, and no phase collapse under 100% aqueous conditions. Ideal for use with LC/MS, these columns maintain selectivity with reduced concentrations of buffers and additives.

Supplier: VARIAN

Polaris™ C18-ether phase has a rapid high resolution separation based on ultra pure silica to which alkyl chains and polar modifications are attached.

Bond Elut™ NH₂ is a weaker anion exchanger than sorbents such as SAX (a quaternary amine sorbent that is always charged) and is therefore a better choice for retention of very strong anions, such as sulfonic acids, which may retain irreversibly on a SAX sorbent. Similar to Diol and SI sorbents, Bond Elut™ NH₂ is excellent for the separation of structural isomers.

Supplier: VARIAN

Bond Elut™ SAX is a strong anion exchange sorbent ideally suited for the extraction of compounds such as carboxylic acids, which may not retain effectively on weak anion exchange sorbents. The sorbent is supplied in the chloride counter ion form. You can modify the selectivity of the phase by replacing the chloride ion with other anions, such as acetate and hydroxide.

Bond Elut™ C18 OH is a non-end capped version of the octadecyl bonded phases that enables the silanols on the silica surface to be more active. This low-load C18 has well-controlled silanol activity that permits the fractionation of metabolites and enhances retention of basic compounds compared to an endcapped C18. The pore size makes it a good choice for peptide extraction.

Supplier: CHIRAL TECHNOLOGIES

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: 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: Thermo Fisher Scientific

HyperSep™ Retain™-CX polymeric SPE material is a high purity, highly porous, polystyrene DVB material partially functionalised with sulphonic acid groups to give balanced retention of basic and non polar analytes. HyperSep™ Retain™-CX is ideal for the retention of a wide range of drugs of abuse, including basic and neutral drugs.

Supplier: VARIAN

Bond Elut™ ENV, a PS/DVB polymer, is designed for the extraction of polar organic residues. It contains 125 μm spherical particles with a high degree of cross linking, advantageous for high volume, fast flow-through applications.

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: 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

These columns offer enhanced retention of polar and hydrophilic analytes. Based on Core Enhanced Technology, they provide fast, high resolution separations without the elevated back pressures required by sub-2 µm particles.

Supplier: VARIAN

Alumina, like silica, is an extremely polar sorbent. The alumina surface tends to be slightly more stable under high pH conditions than unfunctionalised silica. The small particle size of the Bond Elut™ Alumina range ensures high extraction efficiency even when small bed masses are used.

Using proprietary bonding technology, the Cogent C8 300™ has a C8 chain bonded directly to the 5 µm, 300A TYPE-C™ silica surface with two separate points of attachment resulting in silcon-carbon bonds.

Supplier: VARIAN

Bond Elut™ C8 is very similar in properties to C18, but is not as retentive for non-polar compounds, due to its shorter hydrocarbon chain, and therefore reduced carbon loading. C8 is an excellent replacement for C18 when analytes are too strongly retained for effective elution. The potential for polar interactions is somewhat higher than for C18 because there is less coverage of the silica surface. These polar interactions are not, however, a significant property of C8.

HyPURITY™ C18 columns are ideal for chromatography of large peptides, small molecules, with unbeatable peak shape for all sample types. The homogeneous surface ensures uniform bonding coverage and eliminates silanolanalyte interactions that cause poor peak shapes for bases, acids and chelating compounds.

Supplier: Thermo Fisher Scientific

These reversed phase columns were developed in conjunction with the Vanquish™ UHPLC system to take advantage of the system's extended pressure capabilities and robustness. The result is a new level of separation, speed and throughput that solve analytical challenges in liquid chromatography and LC-MS analyses.
