Determination of Polycyclic Aromatic Hydrocarbons in Sediment by Pressure-Balanced Cold Fiber Solid Phase Microextraction
(American Chemical Society, 2017-09-20)An improved performance of the cold fiber solid phase micro extraction (CF-SPME) technique was accomplished with the use of the pressure balanced procedure. In order to obtain a pressure-balanced state during extraction ... -
Matrix compatible solid phase microextraction coating, a greener approach to sample preparation in vegetable matrices
(Elsevier, 2017-09-01)This work proposes the novel PDMS/DVB/PDMS fiber as a greener strategy for analysis by direct immersion solid phase microextraction (SPME) in vegetables. SPME is an established sample preparation approach that has not yet ... -
New Calibration Approaches in Solid Phase Microextraction for On-Site Analysis
(University of Waterloo, 2004)Calibration methods for quantitative on-site sampling using solid phase microextraction (SPME) were developed based on diffusion mass transfer theory. This was investigated using adsorptive polydimethylsiloxane/divinylbenzene ... -
Optimization of Solid Phase Microextraction for Determination of Disinfection By-products in Water
(University of Waterloo, 2012-04-17)A new technique for sample preparation and trace analysis of organic pollutants in water using mixed-phase thin film (MPTF) devices, combined with direct thermal desorption, cold trapping, gas chromatography-mass spectrometry ... -
Strategies to Improve Solid Phase Microextraction Sensitivity: Temperature, Geometry and Sorbent Effects
(University of Waterloo, 2013-04-24)Solid phase microextraction (SPME) has been widely used in a variety of sample matrices and proven to be a simple, fast and solvent-free sample preparation technique. A challenging limitation in the further development of ...
