TMA/Norcal <br /> The sample is analyzed for waste oil by following a modified EPA <br /> Method 3510 extraction procedure. The sample is extracted three <br /> (3) times with hexane. The solvent is removed from the combined <br /> extracts and carbon disulfide is added . The solution is <br /> injected into a gas chromatograph fitted with a flame ionization <br /> detector . Quantitation is performed , as total hydrocarbon <br /> response, against a solution made from a known concentration of <br /> light machine oil. The limit of detection for this method of <br /> analysis is five parts per million (mg/kg) . <br /> The sample is analyzed for volatile halocarbon compounds and <br /> ethylene dibromide by following a modified EPA Method 601 <br /> procedure. The chlorinated compounds are analyzed with a Hall <br /> detector . Quantitation is performed against solutions made from <br /> known concentrations of halocarbon compounds . <br /> The organic lead concentrations of the samples are measured on <br /> the methyl isobutyl ketone extract , using spectroscopic <br /> techniques . The procedures are derived (based on) from U.S . <br /> Environmental Protection Agency methods. <br /> The volatile organic results are shown in Table II , while all <br /> other results are summarized in Table I . <br /> Submitted by: <br /> Robert B.
