The sample is to be compared to "Sloan Ct V [U8D1410-01] according to COC <br /> U8D1412. <br /> On April 16, 2008 a diluted sample,(12.9mg/ 1.5ml)was analyzed by gas chromatography/mass <br /> spectrometry under the conditions of EPA Method 8270C Semivolatile Organic Compounds by GUMS. <br /> This method is designed to look for part-per-billion levels of organic compounds having boiling points <br /> between 150° -300°C. The GC/MS software utilizes the National Bureau of Standards 75K library that <br /> contains the reference spectra of 75,000 common natural and synthetic organic compounds. <br /> On April 17, 2008 the sample data was reviewed and compared to "Sloan Ct 1" U81)14 10-01 sample <br /> and along with diesel, motor oil and mineral oil standards. The samples U8D1410-01 and U8D1412-03 <br /> exhibited a similar chromatography pattern to each other, and both samples closely resembled motor oil. <br /> In summary based on the data,the unknown dark brown liquid of sample U81)1410-01 "Sloan Ct 1 " <br /> and the unknown dark brown liquid of sample U01412-03 "41008-03" are similar and could be the <br /> same product. This was strictly a qualitative analysis. <br /> Mario D'Onofrio Donna Keller <br /> Chemist Laboratory Director <br /> Certification 4 2585 <br />
