Feasibility of using laser induced breakdown spectroscopy for quantitative measurement of calcium, magnesium, potassium and sodium in meat

12-Jun-2018 | Flavio De Oliveira Leme; Daniel Menezes Silvestre; Angerson Nascimento; Cassiana Seimi Nomura, Journal of Analytical Atomic Spectrometry, 2018

The aim of this work is to demonstrate the potential of a commercial laser induced breakdown spectroscopy (LIBS) system for quantitative determination of calcium, magnesium, potassium and sodium in bovine and chicken meat. Bovine and chicken meat are important sources of nutrients in human diet, ...

Spectral intensity clamping in linearly and circularly polarized femtosecond filament-induced Cu plasma

12-Jun-2018 | Qiuyun Wang; Anmin Chen; Ying Wang; Laizhi Sui; Suyu Li; Mingxing Jin, Journal of Analytical Atomic Spectrometry, 2018

This study investigated linearly and circularly polarized femtosecond filament-induced breakdown spectroscopy (FIBS). The spectral intensity with circular polarization along the filament propagation distance was more stable against small perturbations compared with linear polarization. ...

Direct measurement of multi-elements in high matrix samples with a flow injection ICP-MS: application to the extended Emiliania huxleyi Redfield ratio

06-Jun-2018 | Qiong Zhang; Joseph T. Snow; Phil Holdship; David Price; Paul Watson; Rosalind E. M. Rickaby, Journal of Analytical Atomic Spectrometry, 2018

The quotas of a limited number of trace elements in the extended Redfield ratios have been determined before and thought to reflect the requirements of phytoplankton. However, these quotas are found to be quite variable under different environmental conditions, suggesting that the cellular trace ...

Precise isotope analysis of tellurium by an inductively coupled plasma mass spectrometry using a double spike method

05-Jun-2018 | Yusuke Fukami; Jun-Ichi Kimura; Katsuhiko Suzuki, Journal of Analytical Atomic Spectrometry, 2018

This paper presents an analytical technique to determine the concentrations of Te and Se, and the stable isotope composition of Te. The outlined analytical protocol combines Se single-spike and Te double-spike methods to determine the Se and Te concentrations using the isotope dilution method and ...

A modified ZSM-5 zeolite/Fe2O3 composite as a sorbent for magnetic dispersive solid-phase microextraction of cadmium, mercury and lead from urine samples prior to inductively coupled plasma optical emission spectrometry

01-Jun-2018 | Paola Baile; Lorena Vidal; Miguel Ángel Aguirre; Antonio Canals, Journal of Analytical Atomic Spectrometry, 2018

The purpose of this work is to present a simple, fast, cost effective and environmentally friendly magnetic dispersive solid-phase microextraction (MDSPME) method, employing a composite based on ZSM-5 zeolite decorated with iron oxide magnetic nanoparticles (i.e., ZSM-5/Fe2O3) as a valuable ...

Use of an inline dilution method to eliminate species interconversion for LC-ICP-MS based applications: focus on arsenic in urine

01-Jun-2018 | C. Derrick Quarles; Patrick Sullivan; M. Paul Field; Scott Smith; Daniel R. Wiederin, Journal of Analytical Atomic Spectrometry, 2018

Measuring arsenic in urine provides important information for clinical and epidemiological studies. While many researchers have studied ways to improve sample storage and understand why arsenic species undergo species interconversion, none have investigated inline dilution as a solution for ...

The combined measurement of 87Sr/86Sr isotope ratios and 88Sr/85Rb elemental ratios using laser ablation MC-ICP-MS and its application for food provenance studies: the case for Asturian beans

01-Jun-2018 | Aida Reguera-Galan; Mariella Moldovan; J. Ignacio Garcia Alonso, Journal of Analytical Atomic Spectrometry, 2018

The spectral interference of 87Rb on 87Sr for the measurement of 87Sr/86Sr isotope ratios in solid samples by laser ablation multicollector (MC)-ICP-MS could be corrected by combining the transient signal of the sample with a Rb pulse from the nebulisation of a pure Rb standard. This dual sample ...
