Rapid sampling using 3M membrane technology. Innovative Technology Summary Report
The 3M-Empore (TM) High Performance Extraction Disks have become the solid-phase extraction industry standard for meeting U.S. EPA requirements for water analysis of various analytes, including Cs, Sr, Ra, Tc, and U as well as several non-radionuclides including Pb, Hg, Sb, and As. These disks utilize adsorbing particles embedded in a membrane, greatly simplifying radiometric sampling and analysis. After liquid samples are passed through the disks, the disks are placed onto planchets or into liquid-scintillation vials for radiometric counting. For field use they are available in Rapid Liquid Sampler (RLS) form; this is a rugged, color-coded, disposable plastic holder (2-1/8' diameter), which readily adapts Rad Disks to commercial devices such as the Isco field sampler and 3M attended field sampler.
