Solid phase extraction cartridges, Bond Elut™ C2

Supplier: VARIAN
Description: Bond Elut™ C2 is a fairly non-polar sorbent because of the short chain length of the functional group. C2 is often used during the process of method development if analytes are retained too strongly on a C8 or C18 phase. The polarity of C2 is slightly lower than a cyano phase for polar interactions.

QuEChERS dispersive kits

Supplier: Agilent
Description: Step 2: Dispersive SPE cleanup
Select the dispersive SPE kit suited to the type of food being analysed and the method you are following. In this step, an aliquot of the sample extract from step one (see QuEChERS extraction kits) is added to a 2 or 15 ml centrifuge tube containing a small amount of SPE sorbent and MgSO₄. The sorbent will pull out interfering matrix materials from the sample, while the MgSO₄ helps remove excess water and improve analyte partitioning.

Solid phase extraction cartridges, Bond Elut™ Alumina

Supplier: VARIAN
Description: Alumina, like silica, is an extremely polar sorbent. The alumina surface tends to be slightly more stable under high pH conditions than unfunctionalised silica. The small particle size of the Bond Elut™ Alumina range ensures high extraction efficiency even when small bed masses are used.

Solid phase extraction cartridges, Bond Elut™ PRS

Supplier: VARIAN
Description: Bond Elut™ PRS is a strong cation exchange sorbent that is also relatively high in polarity. With no appreciable degree of hydrophobicity, in non-polar solvents, PRS is capable of polar and hydrogen bonding interactions. Due to the very low pKa of PRS, a high ionic strength eluent must be used, and so the use of PRS is recommended for weaker cationic species such as pyridinium compounds.

Solid phase extraction cartridges, Bond Elut™ LMS

Supplier: VARIAN
Description: Bond Elut™ LMS polymeric sorbent lets you elute without having to add amine modifiers, buffers, or acids. The elimination of secondary interactions means that elution of analytes can be achieved with pure organic solvents or HPLC mobile phase-compatible solvent mixtures of low ionic strength. These characteristics are crucial to allow compatibility with LC/MS or other delicate analytical techniques.

C18 SPE cartridges, Bond Elut™

Catalog Number: (HEWL12256001B)
Supplier: Agilent
Description: Bond Elut™ C18 is a hydrophobic silica sorbent. C18 is commonly used for non-polar compounds. Bond Elut™ C18 is endcapped to reduce interactions with silanol groups.

Solid phase extraction cartridges, Bond Elut™ Certify II

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.

Solid phase extraction cartridges, EnvirElut™

Supplier: VARIAN
Description: EnvirElut™ sorbents are specially designed for the extraction of a wide range of compounds from aqueous matrices. EnvirElut™ PAH and Pesticides are available in standard SPE straight barrel cartridges, which can be used on conventional vacuum manifolds such as the Vac Elut SPS 24.

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™ AccuCAT

Supplier: VARIAN
Description: Bond Elut AccuCAT cartridges are mixed bed SPE cartridges consisting of a strong cation exchange (SCX) and a strong anion exchange (SAX) sorbent packed into one bed. AccuCAT is effective for the extraction of acidic, basic and neutral analytes from urine and other biological samples. AccuCAT is particularly effective for catecholamine extraction from bio fluids.
