“…This is caused by: (i) ion scattering, (ii) reaction with the cell gas (e.g. Ar + with H 2 ) and/or (iii) the use of a decelerating potential barrier [14]. Analyte ions are also affected by scattering, but they are less influenced than polyatomic ions due to their smaller size.…”

Evaluation of the multi-element capabilities of collision/reaction cell inductively coupled plasma -mass spectrometry in wine analysis, Talanta, http://dx.doi.org/10.1016/j.talanta. 2014.05.008 This is a PDF file of an unedited manuscript that has been accepted for publication.

AbstractThis work explores the multi-element capabilities of inductively coupled plasma -mass spectrometry with collision/reaction cell technology (CCT-ICP-MS) for the simultaneous determination of both spectrally interfered and non-interfered nuclides in wine samples using a single set of experimental conditions. The influence of the cell gas type (i.e. He, He + H 2 and He + NH 3 ), cell gas flow rate and sample pre-treatment (i.e. water dilution or acid digestion) on the background-equivalent concentration (BEC) of several nuclides covering the mass range from 7 to 238 u has been studied. Results obtained in this work show that, operating the collision/reaction cell with a compromise cell gas flow rate (i.e. 4 mL min -1 ) improves BEC values for interfered nuclides without a significant effect on the BECs for non-interfered nuclides, with the exception of the light elements Li and Be. Among the different cell gas mixtures tested, the use of He or He + H 2 is preferred over He + NH 3 because NH 3 generates new spectral interferences.2 No significant influence of the sample pre-treatment methodology (i.e. dilution or digestion) on the multi-element capabilities of CCT-ICP-MS in the context of simultaneous analysis of interfered and non-interfered nuclides was observed.Nonetheless, sample dilution should be kept at minimum to ensure that light nuclides (e.g. Li and Be) could be quantified in wine. Finally, a direct 5-fold aqueous dilution is recommended for the simultaneous trace and ultra-trace determination of spectrally interfered and non-interfered elements in wine by means of CCT-ICP-MS. The use of the CCT is mandatory for interference-free ultra-trace determination of Ti and Cr. Only Be could not be determined when using the CCT due to a deteriorated limit of detection when compared to conventional ICP-MS.

A novel three rod (tripole) ion optic to which three AC voltages with symmetrically delayed phase shifts were applied to each electrode. We studied its ion guiding, focusing, and mass filtering capabilities by SIMION ver. 7.0 computer simulations. An electric field mathematical model was developed to calculate the pseudopotential of the tripole radial AC force. The tripole showed stable ion guiding for wide ranges of AC amplitude; better collisional focusing than hexapole and octapole and similar focusing as quadrupole (rod pole). Also, the ion optic clearly showed interesting mass filtering potential when the phase shift was asymmetrically delayed. The symmetric shape of the pseudopotential field explained the tripole ion guiding and focusing capabilities. For mass filtering, the pseudopotential was asymmetric and its effect was balanced with DC voltage to separate the ions, depending in their masses. The resolution was much lower than quadrupole but useful when rough filtering was required. (J Am Soc Mass Spectrom 2007, 18, 413-421)

Measuring the concentration levels of trace and ultratrace elements in different samples is an important analytical task in environmental, biological, clinical, as well as industrial studies. Furthermore, the increasing recognition of species‐dependent behavior of elements in a given system has imposed the need for speciation analysis. Thus, the identification and/or quantification of individual compounds is required for elements in their naturally occurring forms, those produced and/or emitted from different anthropogenic activities, as well as the products of species degradation or biotransformation. The two most commonly used tools to deal with such analyses are plasma‐spectrometry techniques, namely inductively coupled plasma optical emission spectrometry (ICP‐OES) and inductively coupled plasma mass spectrometry (ICP‐MS). The suitability of these two techniques relies on their multielemental capabilities, high selectivity, wide dynamic range, high sample throughput, absence of chemical interferences, and easy coupling with different separation techniques. Consequently, applications of these techniques encompass both the determination of total element concentration and the specific detection of elements in different speciation schemes. In this article, the technical background of ICP‐OES and ICP‐MS is introduced, highlighting the capabilities and limitations of each technique. Different sample introduction systems are briefly presented and some applications for element analysis in inorganic and organometallic chemistry are reviewed.
