The Analysis of 1,4-Dioxane for EPA Method 522 and UCMR 3

This Application Note will demonstrate the extraction of
1,4-Dioxane from an aqueous matrix using Option 1 of
EPA Method 522 for 500 mL initial volume sample. It will
make use of the SmartPrep Cartridge Extraction System to
produce a valid Initial Demonstration of Precision (IDP)
and Initial Demonstration of Accuracy (IDA). The
SmartPrep Extraction System can extract 6 samples
unattended when using the bottle rinse mode and 12
samples unattended when not in bottle rinse mode. In this
case, the SmartPrep will be made to run without the use of
the optional bottle rinse mode to maximize sample
throughput. All the flow rates were developed and
programmed into the SmartPrep to obtain the highest
recovery of the target
