“…This carrier effect has already been well documented to be especially relevant for volatile elements, for which the transport efficiency in the absence of any modifier is poor. [28][29][30] For the rest of the elements, the sensitivity does not change significantly up to 200 ng of Pd. For higher amounts, the sensitivity seems to decrease, possibly as a result of overstabilization (the signals clearly show more tailing).…”

This paper reports on the performance of solid sampling-electrothermal vaporization-inductively coupled plasma mass spectrometry for the direct multi-element analysis of two different perfluorosulfonic acid/TFE copolymer samples, which were selected in order to test the potential of this technique for routine control of fluorocarbon polymers. Careful selection of the most suitable isotopes permits the reliable monitoring of the analytes of interest: Cr, Cu, Fe, K, Mn, Pb and Zn. The use of Pd as chemical modi. er allows stabilization of all of these analytes during the pyrolysis step (at 800 degrees C), enabling adequate matrix removal, while the use of a high vaporization temperature (2700 degrees C) is required for the efficient simultaneous vaporization of these elements. Moreover, the 105 Pd 1 signal can be used as internal standard, correcting for possible sensitivity drifts. Under these conditions, straightforward calibration with aqueous standard solutions was feasible for all of the elements investigated. The method thus developed exhibits interesting features, such as a low detection limit (ng g(-1) range) for most elements, a high sample throughput (15 min per determination), a low sample consumption (a few milligrams only), precision values usually in the 7-12% RSD range and the absence of any sample pretreatment, with the subsequent lower risk of analyte losses or contamination. Therefore, it seems to offer a promising alternative for the laborious procedures currently in use for analysis of these complex samples

“…The latter either consists of a filament (of graphite, Ta, W, or Re) under an enclosure (Hall, Jefferson, & Michel, 1988) or a graphite furnace (Fig. 5) of the type used with AAS (Grégoire, 2000). Following sample injection, the temperature of the filament or graphite tube is increased in steps to desolvate the sample, ash the matrix and then vaporized the analyte.…”

“…Some examples of ETVapplications to solid samples are included in Table 3 and more examples can be found in the recent review by Resano, Vanhaecke, and de Loos-Vollebregt (2008). The book chapter by Grégoire (2000) also contains examples in addition to providing a thorough description of ETV and its many features. Finally, the ETV can also be used to obtain real-time information on volatile compounds in solids, such as volcanic eruption products, as the elements released while the sample is heated can be continuously monitored by ICP-MS (Richner et al, 1994).…”

This article reviews the numerous ways in which inductively coupled plasma mass spectrometry has been used for the analysis of environmental samples since it was commercially introduced in 1983. Its multielemental isotopic capability, high sensitivity and wide linear dynamic range makes it ideally suited for environmental analysis. Provided that some care is taken during sample preparation and that appropriate calibration strategies are used to circumvent non-spectroscopic interferences, the technique is readily applicable to the analysis of a wide variety of environmental samples (natural waters, soils, rocks, sediments, vegetation, etc.), using quadrupole, time-of-flight or double-focusing sector-field mass spectrometers. In cases where spectroscopic interferences arising from the sample matrix cannot be resolved, then separation methods can be implemented either on-or off-line, which can simultaneously allow analyte preconcentration, thus further decreasing the already low detection limits that are achievable. In most cases, the blank, prepared by following the same steps as for the sample but without the sample, limits the ultimate detection limits that can be reached.

“…Matrix components, modifiers or added physical carriers, covolatilized with the analyte, may change the transport efficiency and also the pyrolysis curve shape. It is known that the Cd intensity signal is strongly suppressed by matrix components [38], however this is compensated by the ID calibration. An additional study was carried out by determining the concentrations of Cd, Se and Tl in the slurry of the certified reference sediment PACS-2, using different pyrolysis temperatures, without and with modifiers.…”
