Two different sample preparation methods were used and optimised. The GC-MS method was used for various food matrices like breads, potato crisps, potato crackers, french fries. The UPLC-MS method was used for analysis of coffee. The limit of detection and limit of quantification for acrylamide were 7 &micro;g.kg<sup>-1&nbsp;</sup>and 20 &micro;g.kg<sup>-1</sup>&nbsp;by GC-MS, 9 &micro;g.kg<sup>-1&nbsp;&nbsp;</sup>and 30 &micro;g.kg<sup>-1&nbsp;</sup>by UPLC-MS. For both methods the reproducibility, given as relative standard deviation was&nbsp;<&nbsp;5% , and the recovery was&nbsp;close to 100 %.&nbsp;</p> <p>&nbsp;</p> <p><strong>doi:10.5219/61</strong></p> <br /><p>&nbsp;</p></div></span>
