ABSTRACT
Microwave Assisted Extraction offers significant benefits over conventional techniques like soxhlet and sonication for the extraction of SVOCs from environmental samples. These benefits include higher throughput, cost savings, reduced solvent usage, safer work environment and most importantly reduced run times while yielding accurate and reproducible data. Microwave Assisted Extractions reduce run times to an average of 20 minutes as opposed to a several hours with the conventional techniques. Even with reduced extraction times, several steps are still necessary to complete the back-end clean-up of the samples run. Environmental laboratories have fundamentally embraced the technology switch but are still experiencing hesitation from the additional preparation steps and time- consuming cleaning that goes along with first generation techniques.
This presentation will show the differences in sample preparation, clean-up and data between conventional microwave extractions and the key changes necessary in the following areas for:
*Reduced sample prep time
*Reduced number of preparation steps
*Elimination of run to run sample contamination
*Seamless move to array of testable organic compounds
