Determination of Total Mercury in Sediments by Microwave-assisted Digestion-Flow Injection-Inductively Coupled Plasma Mass Spectrometry

Development of an ID ICP-MS reference method for the determination of Cd, Hg and Pb in a cosmetic powder certified reference material

“…8 It seems that Hg, even at relatively low concentrations, adheres to the walls of the introduction system, causing contamination of subsequent samples. 8 It seems that Hg, even at relatively low concentrations, adheres to the walls of the introduction system, causing contamination of subsequent samples.…”

“…8 It seems that Hg, even at relatively low concentrations, adheres to the walls of the introduction system, causing contamination of subsequent samples. 11 Another used a combination of flow injection sample introduction and either Triton X-100/ammonia/ ethylenediamine tetraacetic acid 8,12,13 or 2-mercaptoethanol 14 as the carrier solution. There have been attempts to minimize these memory effects.…”

Selective Reduction Method for Separate Determination of Inorganic and Total Mercury in Mussel Tissue by Flow-Injection Cold Vapor Technique

“…These methods are based on a wide range of analytical techniques such as neutron activation analysis (NAA) (Dermelj and Byrne, 1997;Feng et al, 1996), inductively coupled plasma mass spectrometry (ICP-MS) (Woller et al, 1997;Yoshinaga and Morita, 1997), inductively coupled plasma atomic emission spectrometry (ICP-AES) (Campos et al, 1997), microwave-induced plasma atomic emission spectrometry (MIP-AES) (Costa-Fernandez et al, 1995), electrothermal atomic absorption spectrometry (ETAAS) (Burrini and Cagnini, 1997;Dobrowolski and Mierzwa, 1996), cold vapor atomic absorption spectrometry (CV-AAS) (Aduna de Paz et al, 1997;Bortoli et al, 1995;Doerr and Deinzer, 1997;Kingston and Mclntosh, 1995;Lippo et al, 1997;Matthiessen, 1996;Murphy et al, 1996;Navarro et al, 1992;Ombaba, 1996;Pasquini et al, 1988;Rodriguez et al, 1994;Samanta and Chakraborti, 1997;Saraswati et al, 1995;Schintu et al, 1992;Schnitzer et al, 1995;Tahan et al, 1993Tahan et al, , 1995Tinggi and Craven, 1996;Zhou et al, 1996), and atomic fluorescence spectrometry (AFS) (Brahma et al, 1997;D'Ulivo and Rapsomanikis, 1997). The most wide spread technique for the determination of mercury is CV-AAS because of its high sensitivity, absence of spectral interference, relatively low operation costs, simplicity, and speed .…”

Determination of mercury traces in products of TiO2 manufacturing

“…Speciation of mercury varies in different kind of samples which greatly influence method of sample preparation and digestion [2]. The most common methods for digestion of mineral samples (sediment, soil, rocks, ores) include digestion with a mixture of acids promoted by conventional [2][3][4], or microwave heating [2,5]. Some authors insist on the total digestion of geological samples [6], although others have found that for mercury analysis a partial digestion was sufficient [3].…”
