SPME method development for food analysis

Implementing SPME methods for food analysis

Solid-phase microextraction (SPME) is a fast, solventless, and environmentally friendly technique with application to the complex matrices found in many types of food analysis. SPME, however, is often not applied to its full potential as a result of a lack of proper training or full understanding of SPME method optimization.

Erica A. Souza Silva of the Universidade Federal do Rio Grande do Sul, Brazil, has
joined with Separation Science to present a webinar on how to successfully implement SPME methods for food analysis, including optimizing factors that affect SPME efficiency, considerations for targeted and non-targeted applications, quantitation, and new SPME devices.

Learn to develop and optimize SPME methods

This webinar covers:

  • the basic SPME concepts and relationships
  • modes of operation (direct headspace, membrane-protected)SPME-method-development-food-analysis.jpg
  • how to develop and optimize SPME methods for food and beverage analysis, including those for complex matrices
  • how to minimize sources of errors in order to achieve satisfactory precision and accuracy
  • SPME coating structures
  • how to perform quantitative SPME: calibration methods and choice of internal standard
  • the utility of multivariate chemometric techniques in SPME method development

The utility of SPME over other techniques is demonstrated in applications to pesticide analysis, including coupling SPME and GCxGC-TOFMS for in-vivo metabolomics studies in plant-based food.

SPME methods are valuable to food chemists dealing with complex matrices and laborious sample preparation, as well as analysts who are interested in implementing SPME as a quantitative method or as a high-throughput method to analyze trace levels of pesticides.
