TC Measurement and Elemental Composition Analysis of Fly Ash
The fly ash and incineration ash generated by incineration plants and thermal power plants contain metal oxides such as silica, alumina, calcium oxide and iron as main components, as well as a few percent of incompletely combusted carbon. Elemental and composition analysis of principal components and trace heavy metals is typically conduc ted by ICP, atomi c absorpt ion and X- ray fluorescence, and carbon content is measured using a total organic carbon analyzer (TOC).

| ・Measurement of maximum 1 g samples with up to 30 mg carbon content reduces weighing errors, and errors due to uneven distribution of the sample carbon content ・Measurement of inorganic carbon (carbonate) in solid samples.・Measurement of aqueous samples containing large quantities of suspended substances.・Simply change the onscreen settings to switch between aqueous sample measurement with the TOC-L, and solid sample measurement using the SSM-5000A. |
・Accommodates all types of samples from small to large, from powders to liquids.・Fundamental Parameter Method uses theoretical intensity calculations to determine the composition from the measured intensities. It's a powerful tool for the quantitative analysis of unknown samples in cases where preparation of a standard sample is difficult. | X-ray fluorescence permits qualitative and quantitative analysis of all elements (qualitative analysis of 4Be – 92U,quantitative analysis by FP method) |
