1 October 2012

This Application Note demonstrates the extraction of 1,4-Dioxane from an aqueous matrix using Option 1 of EPA Method 522 for 500 mL initial volume samples. In this study, the SPE-DEX 4790 is used to generate a valid Initial Demonstration of Precision (IDP) and Initial Demonstration of Accuracy (IDA). The SPE-DEX 4790 Extractor with the Envision Platform Controller demonstrates that excellent precision and accuracy can be obtained while performing a single sample extraction in approximately 30 minutes.
