Chloride analysis of botanical samples by ICP-OES

Journal of Analytical Atomic Spectrometry, 2010
A 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.

Contribution to the Application of Kálmán Filtering in ICP-OES

Microchemical Journal, 1997
A 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.

Germanium speciation by LC-HG-ICP/OES

Fresenius' Journal of Analytical Chemistry, 1995
Liquid 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, 2018
Abstract 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

Use and limitations of ICP-OES in wine analysis

Mikrochimica Acta, 1989
At present, some 50 inorganic components in wine can be detected, of which 8 are mineral matter at concentrations down to 1 mg/l, about 25 are trace elements with concentrations of 0.001–0.1 mg/l, and about 20 are ultratrace elements at concentrations below 1 μg/1.

Determination of rhodium: Since the origins until todayICP-OES and ICP-MS

Talanta, 2007
Rh is contained in catalyst in much smaller quantities than Pt. For this reason, the database for this metal with respect to emissions from catalytic converters is much smaller than that for platinum, thus precluding a quantitative risk assessment. Accurate determinations of the rhodium have always been difficult tasks.

The application of ICP-OES to industrial analytical problems

TrAC Trends in Analytical Chemistry, 1982
Abstract ICP optical emission spectroscopy was introduced for multi-element determinations some 15 years ago. Nowadays, its field of application covers the analysis of widely differing materials at every stage of industrial activity.

Trace Element Determination Using ICP-OES

2022
Inductively coupled plasma-optical emission spectroscopy coupled with the benefits of solution chemistry serves as an excellent tool in trace element analysis (TEA) because of its multielement capability, large dynamic range of four to six orders of magnitude, and very high temperature in the range of 7000–10 000 K resulting in virtually complete ...
