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.

Determination of Thorium by ICP-MS and ICP-OES

Radiation Protection Dosimetry, 2001
Natural 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.

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

AAS, ICP‐OES oder Röntgenfluoreszenz

Nachrichten aus der Chemie, 2009
AbstractUm Kinderspielzeug auf giftige Schwermetalle zu untersuchen, bieten sich atomspektroskopische Methoden an. Für Stichproben eignet sich auch die Röntgenfluoreszenz, für die keine Probenvorbereitung erforderlich ist.

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.

การวิเคราะห์ผลของตัวกลางต่อสัญญาณของปรอท และการตกค้างของปรอทที่ความเข้มข้นสูงระหว่างการตรวจวัดด้วยเครื่อง ICP-OES

2016
ปรอท (Mercury (Hg)) เป็นธาตุที่มีอยู่ตามธรรมชาติ สามารถถูกปลดปล่อยออกมาสู่สิ่งแวดล้อมผ่านการกระทำของมนุษย์ ปรอทเป็นธาตุที่มีความเป็นพิษสูงทั้งต่อสิ่งมีชีวิตและสิ่งแวดล้อม ด้วยเหตุนี้ การวิเคราะห์เพื่อหาความเข้มข้นของปรอทในตัวอย่างสิ่งแวดล้อมจึงมีความสำคัญเป็นอย่างยิ่ง โดยทั่วไปแล้วการวิเคราะห์ปริมาณของปรอทในตัวอย่างนั้น จะต้องเริ่มด้วยการดำเนินการย่อยตั

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.

Traceable Phosphorus Measurements by ICP-OES and HPLC for the Quantitation of DNA

Analytical Chemistry, 2007
Measurement of the phosphorus content of nucleotides and deoxyribonucleic acid (DNA) offers an approach to the quantitation of nucleic acids that is traceable to the SI. Such measurements can be an alternative to the commonly used spectroscopic tools that are not traceable.
