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.

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.

Selfpacker® Preparative HPLC Columns

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.

Semi-preparative and preparative silica material, ReproSil®-Pur

Supplier: DR MAISCH

Description: Semi-preparative and preparative spherical silica material allows the clean-up of raw products from mg up to kg amounts, depending on the column ID and length. Spherical materials are easy to pack in columns.
