Solid phase extraction cartridges, Bond Elut™ Certify

Supplier: VARIAN

Description: 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.

SPE columns, ISOLUTE® NH₂

Catalog Number: (470-0100-B)

Supplier: Argonaut Technologies

Solid phase extraction cartridges, Bond Elut™ C1

Supplier: VARIAN

Description: Due to the methyl group and subsequent low carbon load, Bond Elut™ C1 is the least retentive of all alkyl group bonded phases for non-polar compounds. However, due to the extensive end capping of this sorbent to mask polar silanol activity, retention and elution of polar and multi-functional analytes can still be achieved. Typical applications include plasma, urine and aqueous samples.

Solid phase extraction cartridges, Bond Elut™ Plexa PCX

Supplier: VARIAN

Description: 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.

Aluminium oxide for preparative chromatography

Supplier: MERCK PRODUCTION CHEMICALS

Description: The aluminium oxide crystal structure comprises octahedrally and tetrahedrally coordinated aluminium coupled by oxygen atoms. The aluminium oxide surface is covered by free hydroxyl groups. There are different acidic and basic centers (Broenstedt acid, Lewis acid and Lewis basic centers) that result in anion and cation exchange properties. Aluminium oxide exhibits a higher pH-stability than silica gel, especially in the alkaline range. Aluminium oxide occurs in various crystal modifications resulting in different pore diameters.

Solid phase extraction cartridges, Bond Elut™ DEA

Supplier: VARIAN

Description: 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.

Analytical HPLC columns, XBridge™ Phenyl

Supplier: WATERS

Description: XBridge™ Phenyl sorbent can be used over an entire range of mobile phase pH (1 to 12). The trifunctionally bonded Phenyl ligand provides you with a universal column for most HPLC separations and gives you the widest usable pH range, superior low pH stability and ultra-low column bleed.

Sorbents, LiChrosorb®

Supplier: Merck

Description: LiChrosorb® is an irregular shaped silica sorbent. LiChrosorb® packing materials offer the compete programme of non-polar derivatives (RP-8, RP-18, RP-select B) and polar derivatives (Si 60 and Si 100).
