UCT QuEChERS Cited in Agro-Industry Article

July 3rd, 2018

In a recent paper published in Food Chemistry by Claudio Alister et al., (oi: https://doi.org/10.1016/ j.foodchem.2018.06.090), A UCT’s QuEChERS blend containing 4 g magnesium sulfate (MgSO4), 0.5 g of disodium citrate (C6H6Na2O7), 0.5 g of trisodium citrate (Na3C6H5O7) and 1 g of sodium chloride (NaCl) was employed in the primary extraction of  pesticides from prunes. In the secondary clean up stage, 1.5 g MgSO4 and 0.25 g of PSA (UCT Selectra®) were used.


UCT QuEChERS Used for Analysis of Herbicide in Infant Formula

May 15th, 2018

Haloxyfop is a selective herbicide that is used to protect crops such as potatoes and carrots against persistent grasses. In a recent paper authored by Urairat Koesukwiwat et al., (Analytical and Bioanalytical Chemistry https://doi.org/10.1007/s0021), the authors developed and validated a simple method for total haloxyfop analysis in infant formula and related ingredient matrices using UCT’s QuEChERS and liquid chromatography-tandem mass spectrometry (LC-MS/MS).

March 10th, 2017

Preliminary studies have shown that the QuEChERS technique should be considered as a reliable alternative when extracting multiple drug classes from challenging biological matrices. The project described here, explores a modified universal QuEChERS approach for sample clean-up in post-mortem liver, coupled with LC-MS detection, for the analysis of several common prescription and illicit drugs. Read more here
