Abstract Content
EPA Method 8021B describes methods for analysis of volatile aromatics in solid wastes by gas chromatography (GC) with a photoionization detector (PID). This method is designed for analysis of solid wastes and will have to be modified for waste oil analysis. EPA describes headspace, purge and trap, direct injection and vacuum distillation methods. The latter three methods are more suited to solids than oils. In addition, the purge and trap method requires a considerable amount of equipment. Our application is for a small number of daily samples. The headspace method is ideal for oils but will require some modifications for oils.
EPA Method 8082A for the analysis of polychlorinated bi phenyls (PBB’s) involves solvent extraction of solid, tissue or aqueous samples and detection by GC with an electron capture detector or electrolytic conductivity detector. We will modify this method by using a PID for detecting the PCB’s and selecting an extraction solvent that will not be miscible with the oil. For each of the methods, we will determine the precision, accuracy and recovery efficiency from a variety of oils.
