Description:
The paper discusses the analysis of trace-level organic combustion process emissions using novel multidimensional gas chromatography-mass spectrometry (MDGC-MS) procedures. It outlines the application of the technique through the analyses of various incinerator effluent and products of incomplete combustion (PIC) samples using the sequential repetitive heart-cutting method and discusses improvements that are possible using new MDGC-MS procedures. It has only recently been shown by using special MDGC-MS procedures that significant improvements (i.e., with respect to enhanced chromatographic separation and the establishment of quantitative GC zero reference levels) have permitted advanced analytical capabilities for these types of complex samples. It has been demonstrated that sequential repetitive heart-cutting MDGC, with a coupled mass spectrometer, can obtain this valuable analytical information. Even so, large amount of sample are needed for analysis, and total analysis time is quite long. With the introduction of new separation science technologies, a new and different MDGC-MS procedure has been conceived which can accomplish these intricate analyses with a small amount of sample and in a realistic analysis time. MDGC-MS has particular application to EPA's need to characterize in greater detail various hazardous waste combustor emissions.
