Ultra C8 is a conventional monomeric octylsilane column with a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase. These columns are suitable for a wide range of compounds from acidic through slightly basic.

Supplier: Restek

Ultra C8 is a conventional monomeric octylsilane column offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape. It is made of high-purity, type-B silica that minimises activity and creates high-density bonding. These columns are designed for selective and reliable HPLC applications.

Supplier: Restek

Viva C8 columns are conventional monomeric octylsilane columns offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase. These general-purpose C8 columns are suitable for a wide range of compounds from acidic through slightly basic.

Ultra IBD is a polar-embedded column that acts as a strong hydrogen bonder and may be the most versatile column available today. It is compatible with 100% aqueous mobile phases and can be used under reversed-phase or HILIC conditions to retain very polar, ionic compounds in highly organic mobile phases.

Supplier: Restek

These Viva columns are based on a wide pore material designed for optimal large-molecule separations. Base-deactivated spherical silica is useful for normal-phase or HILIC separations. These columns have a narrow distribution around the mean pore size, permitting a larger portion of the silica surface to play a role in the separation.

Supplier: Agilent

Poroshell 120 besteht aus einem oberflächlich porösen Partikel mit einem festen Kieselgelkern und einer porösen Außenschicht. Dieses Partikel bietet eine hohe Effizienz bei niedrigeren Drücken und ist ideal für schnelle oder hochauflösende Trennungen vieler Arten von Analyten.

Supplier: Restek

Bei IBD (intrinsically base-deactivated)-Trägermaterial wird eine polare Gruppe in der Nähe der kohlenhydratgebundenen Phase positioniert bzw. eine polare Gruppe wird in die kohlenhydratgebundene Phase selbst integriert. Einzigartige Selektivität und leistungsfähige Deaktivierung der Basen, wobei der Bedarf nach Zusatzstoffen zur mobilen Phase vermindert oder ganz beseitigt wird.

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: Restek

These biphenyl columns offer a greater degree of dispersion than conventional phenyls and a greater degree of polarizability than phenyl hexyls, creating higher selectivity and a greater range of usability. Because of these heightened interactions, this column shows substantial increases in retention—especially for dipolar, unsaturated, or conjugated solutes—and enhanced orthogonal selectivity when using methanol mobile phases.

Supplier: VARIAN

Bond Elut™ DEA bears some resemblance to Bond Elut™ NH₂ in its properties but with a slightly lower capacity as an anion exchange sorbent. DEA has a moderately non-polar character due to the alkyl side chains on the amino functionality. These groups still afford a medium level of polarity, higher than C₈ but less polar than C₂ or CN-E.

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: VARIAN

Bond Elut™ SCX ist ein starker Kationenaustauscher mit einem sehr niedrigen pKa. Obwohl der pKa dem von Bond Elut™ PRS ähnelt, erhöht das Vorhandensein des Benzolrings in der Funktionsgruppe das Potenzial für unpolare Wechselwirkungen. Diese unpolare Eigenschaft wird besonders wichtig, wenn Ionenaustausch aus wässrigen Systemen durchgeführt wird, wo Selektivität gegenüber Verbindungen mit kationischem und unpolarem Charakter beobachtet wird.

Supplier: Restek

Aqueous C18 is a rugged, reversed-phase column with a well-balanced retention profile. It can effectively retain more types of solutes than a conventional C18 and is ideal for multicomponent LC-MS analyses. The general-purpose Aqueous C18 boasts high reproducibility and compatibility with many mobile phase conditions - even 100% aqueous. And when used with a gradient, it eliminates the all-too-common issue of multiple compounds eluting near the column void time.

The in-line PEEK guard cartridges extend the life of analytical columns by trapping contaminants from the sample and mobile phase, thereby preventing loss of retention. Only PEEK and titanium contacts the mobile phase and sample. This system is ideal for use with proteins or other biopolymers that may be contaminated or absorbed by steel surfaces.
