Combination of QuEChERS and DLLME for GC-MS determination of pesticide residues in orange samples

Food Additives and Contaminants - Part A Chemistry, Analysis, Control, Exposure and Risk Assessment, 2013
A new method combining QuEChERS (quick, easy, cheap, effective, rugged and safe) and DLLME (dispersive liquid-liquid microextraction) followed by gas chromatography-mass spectrometry with selected ion monitoring (SIM) was developed for the simultaneous determination of 19 pesticides from nine chemical groups exhibiting or suspected to exhibit endocrine-

Fast and simple method using DLLME and FAAS for the determination of trace cadmium in honey

Journal of Food Composition and Analysis, 2019
Abstract A novel method for the determination of trace cadmium in honey is presented. It consists of a preconcentration step based on dispersive liquid-liquid microextraction (DLLME) and measurement by flame AAS. Samples are dissolved in water. A mixture of carbon tetrachloride (extraction solvent) and acetonitrile (dispersion solvent) containing ...
