Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

Abstract

SUMMARY OF CONTENTS This review covers developments in 'Atomic Spectrometry'. It covers atomic emission, absorption, fluorescence and mass spectrometry, but excludes material on speciation and coupled techniques which is included in a separate review. It should be read in conjunctionwith the other related reviews in the series. [1][2][3][4][5][6] Sample introductionThis section covers developments in sample introduction for all instrumental methods. LiquidsLiquid sample introduction relates to methods wherein the sample is introduced into the instrument in the form of a liquid, such as through nebulization or into a thermal vaporizer; whereas in vapour generation the sample is initially in the form of a liquid but is converted to a vapour prior to introduction into the instrument. Sample pre-treatment.A general review of on-line preconcentration for ICP-MS has been published by Das et al. 7 , covering solid phase methods and including 63 references. Several reviews of sample pretreatment methods used for atomic spectrometry are worth noting because they focus on specific areas: Kocurova et al. 8and Jain and Verma 9 have reviewed advances in DLLME (53 references) and SDME (407 references) respectively; Zhao et al. the same authors studied the stability of the labelled complexes at different pH and temperature, and when subject to separation using LC. They reported a significant decrease in stability when LC separation was used, and some degradation at 37 °C compared to 2 °C.Li et al. An immunoassay-linked method using gold nano-particles has been developed by Jarujamrus et al. 33 . In this approach the monoclonal antibody-chloramphenicol was attached to a solid support. Antigen-chloramphenicol was labelled with gold nano-particles (10 nm) at pH 9.5, attached to a bovine serum albumin protein and mixed with unlabelled antigenchloramphenicol, which was then added to the antibody-chloramphenicol. for U and Th respectively in water samples.

Atomic Spectrometry Update: review of advances in elemental speciation

“…This latest update adds to that from last year 1 and complements the five other annual Atomic Spectrometry Updates 2,3,4,5,6 . The interest highlighted in the 2018 elemental speciation ASU on the measurement of metal species in biological systems has continued with the publication of a book entitled 'Metallomics: The Science of Biometals,' volume 1055 in the series Advances in Experimental Medicine and Biology 7 .…”

XPS characterization of vanadium carbide species formed during the atomization process in electrothermal atomic absorption spectroscopy

“…Studies about the effects of experimental factors on the processes of electrothermal atomization are of current interest. 21 One important aspect which needs to be investigated is the type of species formed by the solid-state reaction between PGPs and the refractory elements. Previous studies by several techniques 22–25 have suggested that interactions between the carbon surface and the analyte lead to the formation of carbides and thus affect atomization processes.…”

Direct Analysis of Soil Composition for Source Apportionment by Laser Ablation Single-Particle Aerosol Mass Spectrometry

“…These shortcomings for the offline analysis of solid samples require the development of directly on-line analytical methods. Very recently, some new methods to directly analyze solid samples have been reported. , Obviously, laser ablation (LA) sampling dominates the direct analysis of solid samples. Pulsed LA produces an intense burst of energy, which focuses on the surface of solid samples and converts the solid-phase constituents into vapor-phase constituents (vapor and particles) on the nanosecond timescale .…”
