Abstract: A robust and fitted routine method resulting from an analytical optimisation has been applied for the determination of acrylamide in several foods including mainly potato and cereal products. For the sample treatment, different materials were evaluated for filtration and purification of the extract. To increase the performances in terms of sensitivity, a preconcentration to small volume was introduced before liquid chromatography coupled to tandem mass spectrometry analysis on a mu-Bondapak C-18 column using d(3)-acrylamide as internal standard. For identification, relative retention time and two diagnostic ions were monitored. A limit of detection of 10 mu g kg(-1), a limit of quantitation of 20 mu g kg(-1), mean recoveries ranging from 100 to 115%, coefficients of variation from 1.36 to 8.06% for repeatability and from 3.3 to 18.2% for reproducibility within the laboratory and a measurement uncertainty of 42% were obtained during an in-house validation procedure. Results of tests, validation data and Z-score obtained during participation to proficiency studies are presented. (c) 2005 Elsevier B.V. All rights reserved.
