A comparison of the effectiveness of QuEChERS, FaPEx and a modified QuEChERS method on the determination of organochlorine pesticides in ginseng [PDF]

PLOS ONE, 2021
This study provides a review of methods used in the determination of organochlorine pesticides (OCPs) in ginseng and compares the effectiveness of three extraction methods (Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS), a modified QuEChERS and a Fast Pesticide Extraction (FaPEx)) in the analyses of 20 OCPs in ginseng root samples. For each

QuEChERS as alternative extraction procedure in doping analyses

Drug Testing and Analysis, 2023
AbstractQuEChERS is a dispersive solid phase extraction commonly applied in food analysis for residues, such as pesticides or mycotoxins for more than 20 years. Due to the quick and easy sample preparation procedure, a QuEChERS method based on ammonium acetate combined with formic acid in acetonitrile was tested for the preparation of urine samples for

Application of QuEChERS for Determining Xenobiotics in Foods of Animal Origin [PDF]

Journal of Analytical Methods in Chemistry, 2017
The use of pesticides and veterinary drugs results in the appearance of residues of xenobiotics in foods. Thus, several methods have been developed for monitoring them; however, most are tedious and expensive. By contrast, the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) methodology involves a microextraction that yields small samples and

Extraction of ochratoxin A in bread samples by the QuEChERS methodology [PDF]

Food Chemistry, 2012
A QuEChERS method for the extraction of ochratoxin A (OTA) from bread samples was evaluated. A factorial design (2(3)) was used to find the optimal QuEChERS parameters (extraction time, extraction solvent volume and sample mass). Extracts were analysed by LC with fluorescence detection.
