The sample is <br /> to be identified as glycerin according to COC U8E1911. <br /> On May 23, 2008, a diluted sample, (340mg/ 50ml of McOH) followed by a 40x dilution was <br /> analyzed by gas chromatography/mass spectrometry under the conditions of EPA Method 8270C <br /> Semivolatile Organic Compounds by GC/MS. This method is designed to look for part-per-billion levels <br /> of organic compounds having boiling points between 150° - 300°C. The GC/MS software utilizes the <br /> National Bureau of Standards 75K library that contains the reference spectra of 75,000 common natural <br /> and synthetic organic compounds. <br /> On May 27, 2008 the sample data was reviewed using the National Bureau of Standards 75K library. <br /> The chromatogram showed five major peaks include glycerin. The major peaks are as follows in order <br /> of retention time: <br /> 1) Glycerin <br /> 2) Dodecoecanoic acid, methyl ester <br /> 3) Tetradecanoic acid, methyl ester <br /> 4) 9-Hexadecenoic acid, methyl ester <br /> 5) Hexadecanoic acid, methyl ester <br /> In summary based on the data, the unknown brown liquid/solid mixture contains glycerin and fatty <br /> acids. Fatty acids are aliphatic carboxylic acid with varying hydrocarbon lengths with a terminal <br /> carboxyl (-COOH) group. The general formula is R- (CH2)n - COOK This was strictly a qualitative <br /> analysis. <br /> Mario D'Onofrio f Donna Keller <br /> Chemist Laboratory Director <br /> Certification 4 2595 <br />
