Supplier: VARIAN
Description: Bond Elut™ Certify II was developed specifically for the rapid and effective extraction of acidic drugs and metabolites from urine and other biological matrices. Certify II is a mixed-mode cartridge packed with non-polar C8 and strong anion exchange (SAX) sorbent. It has been optimised for acidic drugs such as 11-nor-delta-9-tetrahydrocannibinol-carboxylic acid, salicylic acid, ibuprofen, acetaminophen and other compounds that possess both non-polar and anionic characteristics.

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.

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.

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.

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.

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.

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.
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).

Supplier: MERKLINGER PRAZISION WERKZEUG
Description: This column-packing technology is based on a combination of vacuum suction with subsequent column bed compression that stabilises the packing. A common water-jet pump is used to generate the vacuum. The sorbent slurry is sucked through a packing reservoir into the column by applying low pressure at the bottom end of the column.
