Abstract/Summary:
An ICP-AES Spectral Library for 71 elements has been built with spectra acquired using high purity standards with a UV-Visible Fourier transform spectrometer. This Spectral Library is one of the only spectroscopic data sets that provide complete coverage (i.e. full spectra) for the elements with spectral lines exclusively from ICP-AES. It also provides spectral line intensities for the ICP discharge, which is important for interference considerations. This Spectral Library has superior wavelength accuracy that is inherent to FTS. The overall average wavelength error of the Spectral Library was no greater than 1.05 pm when compared with literature data. As this Spectral Library is stored and distributed in an interactive format, it should bring revolutionary change to the way spectral data can be used.;As such, it is expected that the Spectral Library will find wide range of applications in both industrial and academic environments. Some applications, including scanning spectrum simulation with spectra addition, spectral line identification with spectra subtraction, and assessment of spectral interferences for commercial ICP-AES spectrometers, are introduced as examples. In addition to the MAC based SpectroPlot Program, instructions are provided for two Microsoft Windows based commercial software packages which allow access to the Spectral Library with IBM-PC compatible computers.;Some other related work, including analysis of solution mixtures on the ICP-FTS; direct analysis of solid form Standard Reference Materials with a powder pump coupled to the ICP-FTS; and the calibration with solid standards using the powder pump for the ICP-FTS are also presented in this thesis.
