Preferred label	EF_QuEChERS
Definition	Eurofins provberedningsmetod enligt QuEChERS. Provet extraheras med acetonitril och internstandard (kol-13 märkta PFAS). Efter centrifugering torkas acetonitrilfasen med magnesiumsulfat och natriumklorid. Därefter renas acetonitrilfasen med C18, Fluorisil och ENVI Carb."Solid-phase extraction method for detection of pesticide residues in food. The sample (fruits, vegetables, tobacco, etc.) is homogenized and centrifuged with a reagent and agitated for 1 minute. The reagents used depend on the type of sample to be analyzed. Following this, the sample is put through a dispersive solid phase extraction cleanup prior to analysis by gas-liquid chromatography or liquid-liquid chromatography. F. J. Schenck and J. E.
