RCX-10 carbohydrate analysis columns are designed for the isocratic or gradient separation of carbohydrates. When an isocratic method is used with a conductivity, refractive index, ultraviolet, or pulsed amperometric detector (PAD), mono- and di-saccharides such as glucose, fructose, sucrose and lactose can be quickly determined.

The ZORBAX® Bonus-RP column has a polar amide group embedded in a long alkyl chain. This novel bonding reduces interactions between basic compounds and the silica support, improving peak shape for the most difficult basic compounds. Peak shape and column lifetime are further improved by triple endcapping. In addition, diisopropyl side groups provide steric protection against acid hydrolysis for good lifetime and low pH. The Bonus-RP column provides an alternate selectivity to C18 and C8 alkyl bonded phases.

Supplier: WATERS

An universal, silica based bonded phase with ACQUITY HSS T3 sorbents which is used for the separations for polar and non-polar compounds. It is compatibility with 100% of aqueous mobile phase. It exhibit ultra-low MS bleed, scalable and transferable to HPLC separations.

Poroshell 120 is made with a superficially porous particle that has a solid silica core and a porous outer layer. This particle provides high efficiency at lower pressures and is ideal for fast or high-resolution separations of many types of analytes.

Supplier: WATERS

SymmetryShield™ columns feature Waters' patented embedded polar group technology that shields the silica's residual silanols from highly basic analytes at improves overall peak shape. Additionally, by placing the embedded polar group close to the silica surface, the activity of the surface silanols is further reduced. This imparts selectivity and retention that is different compared to the Symmetry® C18 ligand.

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: YMC

The ProFamily range is manufactured from ultra high purity silica (99,999%), which is then subjected to a special bonding process. Silica with an extremely low metal content is used for the phases of the ProFamily to suppress polar interactions, as metal impurities influence silanol groups to become more acidic.

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.

Monolithic silica technology: A new age in chromatography. Chromolith® columns are based on silica so existing methods can be easily transferred with only minimal investment in new method development work. 'Sol-Gel' technology allows highly porous monolithic rods of silica to be formed. These feature a bimodal pore structure provides a unique combination of macropores and mesopores.

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.

EXtrelut® NT is a specially processed, inert, wide pore kieselguhr with a high pore volume. It has been used for quite some time within research, for the sample preparation of urine, whole blood, plasma and other biological matrices. Other applications include environmental and residue testing such as analysis of industrial, domestic and wastewater. EXtrelut® NT is supplied either pre-packed in cartridges or as a loose sorbent. EXtrelut® NT simplifies liquid-liquid extraction by replacing separation funnels. Using a single step is more efficient, saves solvent, as well as material and time, in contrast to classic funnel separation. The aqueous sample is simply applied to the EXtrelut® NT sorbent. It distributes itself over the chemically-inert matrix so acting as a stationary phase. Subsequently, elution takes place using organic solvents that are non miscible with water. All the lipophilic substances are extracted from the aqueous into the organic phase.
