QuEChERS - Fundamentals, relevant improvements, applications and future trends
Analytica Chimica Acta, 2019The Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) method is a simple and straightforward extraction technique involving an initial partitioning followed by an extract clean-up using dispersive solid-phase extraction (d-SPE). Originally, the QuEChERS approach was developed for recovering pesticide residues from fruits and vegetables, but ...

Evolution and applications of the QuEChERS method
TrAC Trends in Analytical Chemistry, 2015Abstract It is widely recognized that the QuEChERS (quick, easy, cheap, effective, rugged, and safe) method is relevant in pesticide residue analysis. Many official laboratories around the globe are routinely using it due to the advantages encapsulated in its name. However, the frontiers of the application of QuEChERS are not yet established.

Making the case for QuEChERS-gas chromatography of drugs
TrAC - Trends in Analytical Chemistry, 2016Abstract Over the past decade, QuEChERS (quick, easy, cheap, effective, rugged, and safe) has evolved into one of the most widely used extraction techniques for residue analysis. Since its inception, this method is considered particularly adept in the extraction of polar and basic compounds, and hence the majority of methods developed using QuEChERS ...

Application of QuEChERS Method in Spray Deposition Studies
Madras Agricultural Journal, 2012Pesticides are widely used in agriculture for the management of pests (weeds, insects or pathogens). They are generally applied as a spray to cover the target (e.g. an insect, leaf surfaces or part of a plant) with pesticide-laden droplets. Spray may, however, be lost to non- target areas within a crop through deposition on to the soil or on non-target

Polycyclic aromatic hydrocarbons in teas using QuEChERS and HPLC-FLD
Food Additives & Contaminants: Part B, 2018Polycyclic aromatic hydrocarbons (PAHs) are food-processing contaminants considered to be carcinogenic and genotoxic. Due to its drying process stage, teas may be contaminated with PAHs. The aim of the study was to validate an analytical method involving QuEChERS and HPLC-FLD for the determination of PAH4 in teas and evaluate the contamination levels ...
