Determination of Thorium by ICP-MS and ICP-OES
Radiation Protection Dosimetry, 2001Natural thorium (232-Th) has traditionally been measured by radiometric techniques such as alpha and gamma spectrometry. However. with both ICP-OES and ICP-MS instruments becoming relatively common in many analytical laboratories. these techniques have become more acceptable in thorium analysis.

Contribution to the Application of Kálmán Filtering in ICP-OES
Microchemical Journal, 1997A study of emission spectra is presented that investigates the capabilities and the limitations of a multicomponent evaluation method, Kalman filtering, in ICP-OES. Using computer simulation the possible sources of error in concentration estimation were investigated.

Chloride analysis of botanical samples by ICP-OES
Journal of Analytical Atomic Spectrometry, 2010A unique method for chloride analysis of botanical samples by axially viewed ICP-OES with a modified optical system is described. Calibration on the most sensitive wavelength (134.7 nm) between 1 and 200 mg Cl L−1 yielded a curvilinear relationship (R2 = 1.000) across three orders of magnitude.

Germanium speciation by LC-HG-ICP/OES
Fresenius' Journal of Analytical Chemistry, 1995Liquid chromatography-hydride generation-inductively coupled plasma optical emission spectroscopy (LC-HG-ICP/OES) has been used to determine inorganic and organometallic species of germanium. In recent studies these coupled systems has been applied successfully to the speciation of arsenic.

Multielemental quantification in dark chocolate by ICP OES
Journal of Food Composition and Analysis, 2018Abstract In the present work inductively coupled plasma optical emission spectrometry (ICP OES) method for quantification of macro and micro elements in dark chocolate was developed. The plasma characteristics have been evaluated based on simple diagnostics such as the Mg II 280.270 nm/Mg I 285.213 nm (Mg II/Mg I) line intensity ratio. The validation
