Line selection and determination of trace amounts of elements in tungsten by inductively coupled plasma atomic emission spectrometry

Trends in instrumentation and data processsing in ICP-AES : Plenary Lecture

“…Resolution has always been an important feature in AES, particularly with line-rich elements such as U, W, Fe, Co, and rare earth elements. 87 However, it appears that, to facilitate spectra processing, wavelength reproducibility becomes a major request. Spectra processing may be simple to perform like the addition or subtraction of experimental or stored spectra, or may be more complex like deconvolution, 88 Kalman filtering [89][90][91][92][93][94][95][96][97][98] and related procedures, 99,100 or convolution of known profiles and comparison with experimental profiles.…”

Combining single-element stored spectra for the simulation of experimental spectra using multichannel detection-based ICP-AES

“…Because in ICP-AES the spectra are line-rich, in particular when elements such as U, W and Fe are present at high concentrations in the sample for analysis, 1 a selection of the analytical lines has to be made in order to avoid spectral interferences. Besides, appropriate background correction must be conducted for the location of the background points and for the selection of the background correction procedure.…”
