Description: A medium polarity sorbent, Thermo Scientific™ HyperSep™ Cyano Plates are less retentive than silica or diol, and are optimized for the isolation of polar compounds from nonpolar matrices.

Supplier: Thermo Fisher Scientific

Description: Thermo Scientific™ HyperSep SCX Strong Cation Exchanger SPE 96-Well Plates and Individual Wells feature a strong cation exchange sorbent for extraction of charged basic compounds. The use of SPE sample preparation can significantly enhance the robustness and reliability of many biological, pharmaceutical, forensic and environmental applications.

Supplier: Thermo Fisher Scientific

Description: Thermo Scientific™ HyperSep Silica SPE 96-Well Plates and Individual Wells feature a polar sorbent primarily used to retain analytes in non polar matrices, and can effectively separate compounds of very similar structure.

Description: Bond Elut™ C18 is the most hydrophobic, bonded silica sorbent in the Bond Elut™ range. It is the most popular SPE sorbent because of its extremely retentive nature for non-polar compounds. C18 is generally regarded as having the broadest spectrum of retention among bonded silica sorbents, since it retains most organic analytes from aqueous matrices. When analysing small to intermediate molecules, Bond Elut™ C18 can be used for desalting aqueous matrices prior to ion exchange, as salts pass through the sorbent unretained.

Description: PL-Wang is a 4-alkoxybenzylalcohol functionalised polystyrene, prepared from copolymerised PL-CMS, for solid phase peptide synthesis using Fmoc protection strategies and is cleaved using ~ 95% TFA. Particularly useful for solid phase synthesis of small molecules which have a carboxylic acid functional group.

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.

Supplier: VARIAN

Description: Bond Elut™ NH₂ is a weaker anion exchanger than sorbents such as SAX (a quaternary amine sorbent that is always charged) and is therefore a better choice for retention of very strong anions, such as sulfonic acids, which may retain irreversibly on a SAX sorbent. Similar to Diol and SI sorbents, Bond Elut™ NH₂ is excellent for the separation of structural isomers.
