Method 8020. <br /> Final detection was by gas chromatography using a flame ionization <br /> detector as well as a photoionization detector and a 5% AT-1209 1 <br /> 1.75% Bentone 34/Cyromosorb W column and also a Carbopack B/3% ST'- <br /> 1500 column for confirmation. The detection limits for aromatics <br /> in Lab. No. 29166 is higher than normal due to the presence of <br /> Stoddard solvent. We have quantitated and reported the results <br /> for Stoddard solvent in Lab. No. 29166. <br /> Ctrai✓nverierth <br /> i <br /> CU/mlh <br /> 4 Pages Following - Tables of Results <br /> to <br /> .. � - Xlr•:11[[W`I.'71'.I'r11.1 by 1'IIMnM.•,SJI11n.•1•I:r'Y'.' YLI' •vl•II".
