QuEChERS adsorbent CHROMABOND® Diamino / PSA
QuEChERS method and pre-mixes
Within 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 samples
10 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.
Special silica phase for determination of pesticides in food samples with primary and secondary amine functions (PSA).
Particle size 45 µm, specific surface 500 m2/g, pH-stability from pH 2 to 8.
