  Accuracy testing Diesel Range Organic Hydrocarbons in Water

» 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..
