  QuEChERS Clean-up Products


Thermo Scientific* QuEChERS Clean-up Products offer a convenient and effective approach for determining pesticide residues in fruit, vegetables and other foods.

   Product Detail


The QuEChERS method offers the advantages of high recoveries, accurate results and high sample throughput, low solvent and glassware usage, less labor and bench space, lower reagent costs. Yet the procedure is robust and rugged.

The QuEChERS method is a two-step process: extraction followed by clean up. The extraction step products use MgSO4 to reduce water in the sample, along with either NaCl (for most applications) or anhydrous sodium acetate for "base-sensitive" compounds (e.g., folpet or captan). The extraction step products are supplied in a 50mL polypropylene centrifuge tube for convenient extractions. The clean-up step products contain PSA (primary/secondary amine) for the removal of organic acids and polar pigments among other compounds. Some products couple the PSA with endcapped C18 for the removals of most lipids and sterols, or graphitized carbon black for the removal of sterols and pigments such as chlorophyll. A variety of tube formats and bed weights are available to accommodate large and small sample sizes.
  • Determine greater number of pesticides than with standard SPE
  • Easy to use
  • Available in a number of configurations
