' FRIEDMAN & BRUYA, INC. <br /> ENVIRONMENTAL CHEMISTS <br /> Date of Report October 25, 1995 <br />' Date Received October 18, 1995 <br /> Project: U-Haul, PO #709-50 <br /> Date Samples Extracted: October 19, 1995 <br /> RESULTS FROM THE ANALYSIS OF THE SOIL SAMPLE <br /> FOR FINGERPRINT CHARACTERIZATION <br />' BY CAPILLARY GAS CHROMATOGRAPHY <br /> USING A FLAME IONIZATION DETECTOR (FID) <br /> AND ELECTRON CAPTURE DETECTOR (ECD) <br /> Sam le ID GC Characterization <br />' MW-7 @ 20' The GC trace using the flame ionization detector (FID) <br /> showed the presence of low boiling compounds The <br /> patterns displayed by these peaks are indicative of <br />' mineral spirits, Stoddard solvent, paint thinner or <br /> another light petroleum based solvent The low boiling <br /> compounds appeared as a ragged pattern of peaks eluting <br />' from n-C7 to n-C14 showing a maximum near n-Cg The <br /> low boiling product appears to have undergone chemical <br /> or biological degradation due to the presence of broad <br /> peaks and a broad hump of unresolved peaks A distinct <br /> pattern of n-alkanes was not seen for the product A lack <br /> of n-alkanes is also indicative of chemical or biological <br /> degradation <br />' The large peak seen near 25 minutes on the GC/FID trace <br /> is pentacosane, added as a quality assurance check for <br /> this GC analysis There is a second internal standard <br />' peak seen on the GC/ECD trace at about 26 minutes <br /> which is dibutyl chlorendate <br /> 1 <br /> 1 <br />
