“…Likewise, Hydrogen peroxide (H2O2) also have a higher boiling point (150°C) so H2O2 is also a strong oxidizer agent. H2O2 is used together with HNO3 to dissolve substances that are not fully dissolved by HNO3 alone [12,19].…”

In the present work, the microwave digestion procedure for the determination of Ca, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Se, V and Zn in multivitamin/multielement (MVM) preparations used for pregnant women and diabetics employing ICP-MS, was optimized by factorial design 3 3 (27 runs). The microwave digestion conditions temperature (160, 180 and 200ºC), acid mixture volume (3.9, 5.2 and 6.5 ml) and radiation period (10, 15 and 20 min) were selected as factors. Moreover, a multiple response (MR) was built to establish a compromise conditions between the elements. The optimum conditions were found to be 160ºC, 6.5 ml, and 20 min for temperature, acid mixture volume and radiation period, respectively. The procedure was validated using standard reference material (SRM3280) and elements recoveries were found to be in the range 88 -107% and was applied to determination of Ca, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Se, V and Zn in commercial MVM samples obtained from the local market.

“…Two papers by the same group 95,96 described the characterisation and application of a CCP constructed with a molybdenum tubular electrode and either one or two ring electrodes, operated with a flow of 0.4 L min -1 argon and at 275 W power. Under these conditions the degree of ionization was calculated to be between 73-85% for Ca, Cd, Mg and Mn with tworing electrodes.…”

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.

“…Among spectrometric techniques, inductively coupled plasma optical emission spectrometry (ICP-OES) is widely used in the analysis of pharmaceuticals and dietary supplements. [15][16][17][18][19][20] The advantages of this technique relate to extended dynamic range, simultaneous multi-element capability, high sensitivity and low detection limits. 21 As most of spectrometric methods, ICP-OES generally requires conversion of the solid samples into a representative solution that is introduced by pneumatic nebulization into plasma.…”

A free non-spectral interferences method based on inductively coupled plasma optical emission spectrometry was characterized in terms of figures of merit for multielemental determination in multimineral/multivitamin preparations. The method was validated for the determination of Mg, Ca, Cr, Mn, Fe, Cu and Zn based on the analysis of a standard reference material (SRM 3280) and different brands of commercially available multimineral/multivitamin supplements. The study showed that a simple 100-fold dilution of the sample ensures overcoming of non-spectral effects in complex matrices such as multimineral/multivitamin preparations. Detection limits were in the range 0.0009-0.0037 mg g-1. The recovery was within 93%-110% for certified reference materials and 94%-105% for real samples of marketed supplements. Precision of measurements was in the range 1.3-12.1%.
