Day 1

18:30 – 18:55 (CEST) Enhanced Extraction using a combination of Stir Bar Sorptive Extraction and Thin Film-Solid Phase Microextraction

Abstract: The analysis of flavor components faced many challenges due to the complexity of its nature. In this study, a new method combining stir bar sorptive extraction (SBSE) and thin-film solid-phase microextraction (TFSPME) was developed and optimized. Polydimethylsiloxane (PDMS)-coated SBSE and PDMS/carboxen (PDMS/CAR)-coated TF-SPME were used, and both headspace and direct immersion extraction modes were also studied. Using 40 common volatile compounds, the combined method generally showed improvements in terms of linearity range, coefficient of determination, sensitivity and recoveries when compared to SBSE-only or TFSPME-only techniques. Furthermore, despite the combined use of two extraction devices, the repeatability and reproducibility of the combined method were comparable to SBSE-only or TFSPME-only results. Finally, the developed method was being successfully applied onto tea and coffee samples.

18:55 – 19:25 (CEST) Utilizing SPME and SBSE With Automated internal Standard Dosing via Gerstel Robotic Pro MPS for Unknown Samples

Abstract: Many flavor companies are looking to increase efficiencies and reduce waste in the laboratory. Turning to automated, semi-automated and solventless extraction techniques for gas chromatography mass spectrometry (GCMS) analysis is becoming increasingly more common, partly because it reduces solvent usage and waste generation. These techniques include Solid Phase Micro Extraction (SPME) and Stir Bar Sorptive Extraction (SBSE) aka Gerstel Twister ™, Direct Thermal Desorption (DTD), Dynamic Headspace (DHS) and Thin Film SPME (TF-SPME). Using more than one of these techniques on a given sample can yield different results based on the chemistry of the compounds present in the sample and the complexity of the matrix thus providing a more detailed analytical profile. In addition, these techniques are compatible with automated internal standard dosing via the Robotic Pro MultiPurpose Sampler (MPS) which increases both efficiency and accuracy while decreasing waste.
