Qualitative and Quantitative Analysis of Automobile Exhaust Particulates (EDX)
Factory and vehicle emissions are a cause of atmospheric and environmental pollution. They have become important subjects of investigation as concern for the environment has increased over recent years. The Energy Dispersive X-ray (EDX) Fluorescence Spectrometer permits easy analysis of particulates separated and collected from vehicle and factory exhaust, as well as those collected on filter paper. This section gives examples of the quantitative and qualitative analysis of vehicle exhaust particulates.
The Energy Dispersive X-ray Fluorescence Spectrometer directly irradiates the sample with X-rays and measures the energy and intensity of the secondary fluorescent X-rays that are generated. This permits non-destructive characterization of the constituent elements of the sample (qualification) and measurement of their concentrations (quantitation). This method offers easy and rapid identification of elements in solid, powder, and liquid samples, as no chemical pretreatment is required and multiple elements are analyzed simultaneously.
