Optical emission spectrochemical analysis

OPTICAL EMISSION SPECTROCHEMICAL ANALYSIS. In this analytical technique, an optical device is used to analyze radiation from electrically excited sample atoms. The analyzing device provides monochromatic images whose intensities are measured and related to the concentration of the elements within the sample that produces the specific radiation measured. The technique is precise and rapid, and adaptable to solid, powder, or liquid samples. 

Slavin (1971). The book by Slavin (Emission spectrochemical analysis) is an excellent book by the senior member of an atomic spectrometry family on emission spectrochemistry covering important advances since the 1950 s in theory and optical, electronic, measurement and computer technologies. The underlying technique is principally arc/spark emission spectrography/ spectrometry with mention of new excitation sources such as the flame, high-frequency discharge and plasma jet coming into play at that time.

As discussed earlier in this text, x-ray spectra are decidedly simpler than optical emission spectra, but even so, spectral line interferences do occur. Table 8.1 lists several types of spectral line interference commonly encountered in x-ray spectrochemical analysis using wavelength dispersion.
