The 3710 RLS is an ISCO Model 3710 Sampler, specially modified to collect radionuclide samples using 3M Empore™ Rad Disks. The Empore disks selectively trap radionuclides, which are then analyzed to find concentration levels. In addition, the amount of sample flowing through the disk is known, allowing specific loading effects of the pollutant to be determined.
Previously, when water pollutants were present in very small amounts, a technician would have expose the Empore disks to large quantities of sample in the lab to obtain the necessary concentrations. The 3710 RLS eliminates this cumbersome procedure, by placing the Empore disk in the collected sample path on-site. This method has been shown to dramatically reduce turnaround time and overall cost.
A study by Westinghouse Savannah River Company, using ISCO 3710 RLS samplers, showed that “Data collected over a four-month field test period compares very favorably with concurrent laboratory-based analyses and historical data, at a reduction in cost and significant time savings.” Copies of the complete report are available on request.
