Advances in solid-phase microextraction as sample preparation method for food analysis.
(University of Waterloo, 2015-02-25)Within all steps involved in the analytical process, sample preparation is considered the most time-consuming step. Therefore, substantial efforts have focused on the search for automated sample preparation strategies that ... -
Direct immersion solid-phase microextraction analysis of multi-class contaminants in edible seaweeds by gas chromatography-mass spectrometry
(Elsevier, 2018-11-15)The present work aimed at the development of a simple and accurate direct immersion-solidphase microextraction-gas-chromatography-mass spectrometry (DI-SPME-GC-MS) method for simultaneous determination of PAHs, PCBs, and ... -
Exploiting the tunable selectivity features of polymeric ionic liquid-based SPME sorbents in food analysis
(Elsevier, 2018-10-01)In this work, the performances of polymeric ionic liquid (PIL) based solid-phase microextraction (SPME) coatings were assessed for applications concerning food safety and quality. Two different polymeric ionic liquid ... -
Inter-laboratory validation of a thin film microextraction technique for determination of pesticides in surface water samples
(Elsevier, 2017-04-29)The primary goal of the present study is the inter-laboratory evaluation of a thin film microextraction (TFME) technique to be used as an alternative approach to liquid-liquid extraction (LLE). Polydimethylsiloxane/ ...
