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.

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.
