“…The analytical utility of negative ions has been explored in ICP-MS systems, where the halogens have been detected with good sensitivities [14]. There have been relatively few studies on detection of negative ions from a GD in argon [15].…”

“…(Even though in ICP-MS generally positive ions are detected, the use of negative-ion detection as an alternative approach has been evaluated for the analysis of nonmetals such as F, that are likely to form negatively charged species in the ICP or in the extraction process. 40 …”

“…In many cases organic eluents are used and so detection via plasma source mass spectrometry is generally impeded by interferences owing to the presence of carbon (e.g. 40 Ar 12 C 1 on 52 Cr 1 ). 75 Clogging of the sampling orifice is a further problem that arises as a consequence of the high carbon content.…”

“…Multielement analysis of materials and objects in the context of forensic studies or provenance determination has been described in literature as well. [107][108][109][110] The use of LA-ICP-SFMS for the forensic study of glass was described comprehensively by Latkoczy et al 111 Determination of Fe in glass for forensic purposes by LA-ICP-SFMS was performed by Castro et al 112 Polyatomic interferences such as 40 57 Fe 1 , are resolved at a mass resolution of 4000. Ancient glass, for instance, was characterised using LA-ICP-SFMS (single collector) in order to determine the provenance of glass from an excavation in Ephesos/Turkey and to investigate the secret production processes of Art Nouveau glass.…”

ICP-MS is based on the formation of (preferentially monovalent positively) charged atomic ions in an inductively coupled Ar plasma at almost 10 000 K. The ions formed are transferred from the plasma source at ambient pressure into a mass separator operated at high vacuum via a set of cones. The ions are separated according to their mass/charge ratio in the mass separator (quadrupole, magnetic sector field or time-of-flight mass separator). In most cases, the ions are detected using a secondary electron multiplier; in some set-ups (also) a Faraday cup can be used. Single-collector (scanning mass spectrometer usually used for quantitative elemental analysis) or multicollector (static operation of mass spectrometer for precise isotope ratio analysis) configurations can be found (Figures 12.1 and 12.2).

“…Interestingly, many halogens can be detected with ICP-MS as negative ions. Vickers et al [133] have reported LOD between 10 and 400 g/L for halogens by such a method. The authors hypothesized that these ions are created by electron attachment, potentially within the first stage of the mass spectrometer.…”

Current and emerging capabilities of plasma-source mass spectrometry (PS-MS) as it is employed for elemental speciation analysis are reviewed. Fundamental concepts and their advantageous aspects, experimental conditions, and analytical performance are described and illustrated by recent examples from the literature. Novel instrumentation, techniques, and strategies for inductively-coupled plasma mass spectrometry (ICP-MS), microwave-induced plasma (MIP) mass spectrometry, glow-discharge (GD) mass spectrometry, and electrospray ionization (ESI), among others, are described. The use of ionization sources that provide tunable ionization, others that can be modulated between different sets of operating conditions, and others used in parallel is also examined.
