Another Successful DMR QA Study!

Once again, Hydrosphere Research has completed the DMR-QA study with "Acceptable Results" for all test species and all test endpoints. As a lab, we are required to test unknown samples once a year and compare those results to the acceptable analyte ranges for that study. The acceptable range is based on the actual level of analyte in the unknown sample, and on the combined concentration and statistical results from the other participating labs around the country.
