QuEChERS extraction products

Supplier: Thermo Fisher Scientific

The QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) technique is increasingly becoming the technique of choice for the extraction of pesticide residues in fruit, vegetables and other foods. The QuEChERS method offers the advantage of high recoveries, accurate results and high sample throughput, combined with the associated cost savings with low solvent and labour requirements. Yet the procedure is robust and rugged.

Gel filtration chromatography columns, HiLoad™ with Superdex™ Prep Grade

Supplier: Cytiva

HiLoad™ Superdex™ prep grade are prepacked XK columns designed for pre-parative gel filtration. Superdex™ prep grade is a composite matrix of dextran and highly cross-linked agarose. The steep selectivity of dextran, and the high chemical and physical stability of agarose, enable high resolution separations. The chromatography media combines high mechanical strength with high hydrophilicity, allowing high flow rates and minimal non specific interactions.

Solid phase extraction cartridges, Bond Elut™ Certify II

Supplier: VARIAN

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.

QuEChERS dispersive kits

Supplier: Agilent

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.
