Water samples were accurately measured on the UVF-3100 analyzer, calibrated
to Sitelab's EDRO calibration kit.
» The certified spiked
concentration was 3.62 mg/L. Sitelab's DRO result was 3.78 mg/L.
Results below are compared to the DRO in water concentrations reported by 83
participating laboratories using GC-FID or GC-MS instrumentation.
Examples of laboratory DRO methods used in this study: U.S. EPA 8015, 8015B,
8015M, California LUFT, Connecticut ETPH, Florida PRO, Iowa OA-2, Oklahoma
DRO, Maine 4.2.25, NWTPH-Dx and IDNR OA-2..
