Accelerated Solvent Extraction of Plasticizers from Polyvinyl
When developing extraction methods, one way to validate extraction efficiency is to re-extract the same sample and check for remaining analytes. The Dionex ASE system allows the analyst to automate re-extraction for easy method validation. Conclusion This Application Note demonstrates that, for the extraction of the plasticizers discussed above
