Atomic spectrometry update: review of advances in the analysis of clinical and biological materials, foods and beverages

Abstract

This review discusses developments in elemental mass spectrometry, atomic absorption, emission and fluorescence, XRF and LIBS, as applied to the analysis of specimens of clinical interest, foods and beverages. Sample preparation procedures and quality assurance are also included.

Atomic spectrometry update – a review of advances in environmental analysis

“…A novel signal-enhancement strategy for LIBS analysis of soil combined 201 APGD and cylindrical (plasma) connement. The LODs of 2,31,21,35,49,67,43,20 and 18 mg kg −1 for Ba, Cu, Eu, La, Lu, Ni, Ti, Y and Yb, respectively, were signicantly better than the values (10,133,102,175,262,356,246,158 and 105 mg kg −1 , respectively) achievable using conventional LIBS. An alternative approach involved 202 addition of 15% KI to soil samples to increase plasma temperature and electron density.…”

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…The paper discussed how this interaction may occur and gave three possibilities. These were: (1) direct interaction between the laser beam and surface layer, (2) indirect interaction between the expanding plasma originating from the substrate and the surface layer at the crater walls and recasting layers being present aer the ablation step and (3) contaminating the substrate material underneath surface layer. The authors set up a study in which a brass substrate had a layer of stainless steel of thickness 500 mm placed on top.…”

“…It follows on from last year's review 1 and is part of the Atomic Spectrometry Updates series. [2][3][4][5][6] This year's review period has seen a signicant upturn in the number of relevant papers. Increases in number for most sections were noted.…”

Inductively Coupled Plasma-Mass Spectrometry (ICP-MS), a Useful Tool in Authenticity of Agricultural Products’ and Foods’ Origin

“…Trace and rare earth elements have also been shown to play an important role on geographical origin and authenticity of a variety of products including, among others, wheat grains, wines, dairies, olive oils, legumes and meats. Currently, atomic and mass spectrometry which comprise Atomic Absorption Spectrometry (AAS), Atomic Fluorescence Spectrometry (AFS), Flame Atomic Absorption Spectrometry (FAAS), Inductively Plasma Optical Emission Spectrometry (ICP-OES), Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES), and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) are the most common analytical methods for the elemental or multi-elemental determination of food samples [ 12 ].…”
