Webinar: Speaking of SPME... SPME Applications in Food Analysis by Means of a New Matrix Compatible Coating.

Duration: 75 minutes

Description / Abstract

The complexity and diversity food matrices and the need for clean extracts to be injected into analytical instrumentation may imply the use of tedious and time-consuming sample preparation strategies that often are a source of a significant amount of laboratory waste. The development of a new matrix-compatible solidphase microextraction (SPME) coating, namely PDMS/DVB/PDMS, bearing enhanced antifouling properties, enabled the analysis of complex food matrices by direct immersion SPME and helped to overcome issues related to extensive sample pre-treatment and instrumental contamination. This webinar will focus on recent advances made toward the analysis of contaminants in complex food samples by using the new matrix-compatible SPME coating and will describe the optimization of important parameters to be considered when performing DI-SPME.


Speaker Bio
Emanuela Gionfriddo, Ph.D.
Research Associate under Prof. Janusz Pawliszyn, University of Waterloo (ON, Canada)
Emanuela Gionfriddo is currently Research Associate in Prof. Pawliszyn’s research group and manager of the Gas-Chromatography section of the Industrially Focused Analytical Research Laboratory (InFAReL) at University of Waterloo (ON, Canada). She received her B.Sc. (2008) and M.Sc. (2010) in Chemistry and her Ph.D. in Analytical Chemistry (2013) at University of Calabria (Italy). Since 2014, she has been working in Prof. Pawliszyn’s research group: her research focuses on the development and testing of new matrix compatible SPME coatings, compatible with both gas- and liquid- chromatography applications and suitable for direct immersion in complex matrices such as biological fluids and foodstuffs: potential application of these coatings involves the coupling of complementary chromatography platforms for both targeted multiresidue analysis and metabolomics studies. She is also active in the development of new SPME methods for determination of contaminants at trace level in various food, environmental matrices and pharmaceutical supplements by GC-MS, GCxGC-MS and direct coupling with MS. Starting in January 2018, she will be an Assistant Professor of analytical chemistry with the Department of Chemistry and Biochemistry of University of Toledo (OH, USA).
