QuEChERS method and pre-mixesWithin a few years after its devleopment by Anastassiades et al. the QuEChERS method has gained a leading position for determination of pesticide residues in food by GC-MS or LC-MS allowing rapid and cheap clean-up of strong matrix-contaminated samples.Standard clean-up of food samples10 g sample are homogenised with 10 ml acetonitrile. After adding the internal standard the sample is shaken with 4 g MgSO4 and 1 g NaCI and afterwards centrifuged. 1 ml of the supernantant is spiked with 25 mg CHROMABOND® Diamino and 150 mg MgSO4 and shaken again. After centrifugation the supernatant is injected into the GC/MS.Extraction mixtures for sample preparation for determination of pesticides in food samples.MACHEREY-NAGEL offers a number of individually weighed and pre-mixed buffers and extraction mixtures, specially composed for different sample matrices.Mix I and Mix II are extraction mixtures, Mix III to Mix VI are clean-up mixtures.The food samples will be extracted with either Mix I or Mix II.Afterwards they will be purified with one of the following mixtures:Mix III (samples with low fat content; e.g. apples, strawberries),Mix IV (moderate content of chlorophyll and carotinoids; e. g. carrots, lettuce),Mix V (high content of chlorophyll and carotinoids; e. g. bell peppers, spinach),Mix VI (high fat content; e. g. avocados).Every mix is prepacked in a 15 ml centrifuge tube.
