6 UVF-3100 Analyzer Publication No. EPA/600/R-01/080 Evaluated by U.S. EPA in 2001 Ranked highest compared to other screening devices for TPH in soil. Over 200 samples were tested. EPA spent $800,000 on project. Results were compared to split samples sent to certified lab for TPH analysis using 8015 by GC-FID. Sitelab s popular UVF-3100D instrument is fitted with 3 sets of optical filters which are sensitive to different hydrocarbon ranges. Can perform TPH Fingerprinting Lab Certification with NJ DEP Sitelab s laboratory and use of UVF certified from 2009 to NC DENR Regulators approve use of UVF for TPH analysis in UST Guidelines. Sample test kits and calibration kits are used for analysis Page 6 of 28 LSPA Training Course, Feb 2, 2016 Sitelab Corporation
