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.

Elemental composition of pork meat from conventional and animal welfare farms by inductively coupled plasma-optical emission spectrometry (ICP-OES) and ICP-mass spectrometry (ICP-MS) and their authentication via multivariate chemometric analysis.

Meat Science, 2020
The demand of consumers from around the world for natural, nutritional and palatable pork meat is increasing with time. This study analyzed macro (Ca, K, Mg, Na, P), micro (Fe, Zn, Cr, Mn, Ni, Cu, Se, Sr, Cs), trace (Li, Be, V, Co, Ga, Ba, U), and toxic ...

Application of ICP-OES and ICP-MS in materials analyis

2022
Characterization of historical and modern samples is very important in materials engineering. In historical samples, valuable cultural heritage needs preservation and the obtained results dictate decisions on cleaning, conservation and restoration steps.

A simple method for the precise determination of multi-elements in pyrite and magnetite by ICP-MS and ICP-OES with matrix removal

, 2020
A simple, economical, and rapid chemical method was developed for the precise measurement of major and trace elements in bulk pyrite and magnetite. This method, which required only 10–20 mg of sample, used inductively coupled plasma mass spectrometry ...

Determination of elevated concentrations of bromine in serum by ICP-MS and ICP-OES

Journal of Analytical Atomic Spectrometry, 2005
The inorganic and organic components of 100-fold diluted serum enhance the signal of 79Br+ in ICP-MS by about 13%. Sodium and albumin are the main causes of the effect. Different calibration procedures were investigated to compensate for the enhancement interference.

การวิเคราะห์ผลของตัวกลางต่อสัญญาณของปรอท และการตกค้างของปรอทที่ความเข้มข้นสูงระหว่างการตรวจวัดด้วยเครื่อง ICP-OES

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

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.
