UCT's world-class QuEChERS

UCT QuEChERS products are favored by private and government labs on 6 continents.  With our large selection of high quality products and capability to customize UCT QuEChERS products are constantly in high demand.  In addition, all of our QuEChERS products are supported by our superior technical team.

QuEChERS was originally developed by Anastassiades and Lehotay, et al. in 2003, for the extraction and analysis of moderately polar to non-polar pesticides from fruits and vegetables.  At the request of the USDA, UCT became the first commercial producer of QuEChERS kits.  Since then, QuEChERS has been expanded to include the extraction of a huge variety of analytes from nearly every agricultural commodity.
As the scope of QuEChERS has expanded, so has the range of QuEChERS products and applications offered by UCT.  The most novel of our developments is ChloroFiltr®.  ChloroFiltr® is used in the dSPE clean-up step to remove chlorophyll from the QuEChERS extract.  Without ChloroFiltr®, analysts would be forced to use graphitized carbon black (GCB) which also removes planar pesticides.  ChloroFiltr® only removes chlorophyll without removing pesticides.  A second product unique to UCT is the QuICK QuEChERS Push-Thru cartridge.  The cartridge contains magnesium sulfate anhydrous and PSA.  Recoveries are comparable to the traditional dSPE product, but extracts are remarkably cleaner.  With the use of a disposable syringe to “push” the QuEChERS extract through the cartridge, QuICK QuEChERS is much faster than dSPE and a centrifuge is not required.
