摘要

SRNL recently developed a prototype device for the IAEA to prepare particulate samples collected on swipes for laboratory analysis. The Vacuum Aerosol Contaminant Extractor (VacACE) utilizes electrostatic precipitation in lieu of the impaction or ultrasonic solvent extraction methods presently employed by the IAEA to place particles of interest on carbon planchets for investigation. The project was funded by the Intentional Safeguards Projects Office (ISPO) with scope for device design and fabrication, but no scope for validation or testing. Without documented validation of the tool, sample processing and subsequent analysis fidelity cannot be assured. The goal of this project was to determine collection efficacy in a rigorous fashion, demonstrate proof of concept with standardized particulates, and produce a validated VacACE sampling protocol.
