| Abstract: | Abstract: A method has been developed to determine acrylamide in aqueous matrices by using direct immersion solid-phase microextraction (SPME) coupled to gas chromatography–positive chemical ionization tandem mass spectrometry (GC–PCI-MS–MS) in the selected reaction monitoring (SRM) mode. The optimized SPME experimental procedures to extract acrylamide in water solutions were: use of a carbowax/divinylbenzene (CW/DVB)-coated fiber at pH 7, extraction time of 20min and analyte desorption at 210°C for 3min. A detection limit of 0.1μgL−1 was obtained. The linear range was 1–1000μgL−1. The relative standard deviation was 10.64% (n =7). The proposed analytical method was successfully used for the quantification of trace acrylamide in foodstuffs such as French fries (1.2μgg−1) and potato crisps (2.2μgg−1). [Copyright &y& Elsevier] |
