“…Several approaches have been used to overcome this, including use of different chemical modifiers, 38,39 addition of reactive gases, [38][39][40][41][42] use of graphite rod direct sample insertion (DSI) devices, 43 a carbon cup, 44 and vaporization from a filament of W, Re or Ta or from platforms coated with these elements. 45,46 The aim of this study was to develop an ETV-ICP-MS method for the determination of Th, U and Pu in environmental and clinical samples.…”

Carbide formation was minimized using sample vaporization from a tantalum surface for U and additional use of tetrafluoromethane (Freon-23) as a gaseous modifier for Th and Pu. A prior Ca 3 (PO 4 ) 2 coprecipitation provided an enrichment factor of 50, yielding procedural detection limits (LOD) of 0.013, 0.029 and 0.017 pg g À1 for Th, U and Pu, respectively and corresponding absolute LODs of 0.13, 0.29 and 0.17 fg. Recovery of spikes from urine was typically 80%, whereas those from seawater, river water and biological materials averaged 99%. The accuracy of the method was validated by determination of U and Th in NIST SRM 1566b Oyster Tissue and U in a series of NRC natural water CRMs SLRS-4, CASS-4, NASS-5 and SLEW-3. Precision of determination was better than 10% at concentrations of 0.1 ng mL À1.

“…This nding is also consistent with the improved metal release observed in electrothermal vaporization ovens in the presence of Freon. 32 It is worth noting that the formed HF caused signicantly increased Si background resulting in spectral interference of the Ni 221.648 nm emission line. Up to now no visible degeneration of the combustion tube was observed.…”

, and Zr) in volatile organic solvents such as acetone, methyl isobutyl ketone (MIBK), chloroform, dichloromethane, tetrachloroethane or trichloro-trifluoroethane. After combusting the sample aerosol in a commercial carbon analyzer oven in an oxygen-rich atmosphere, carbon dioxide and remaining oxygen were removed from the gas stream prior to the introduction into an inductively coupled plasma optical emission spectrometer (ICP-OES). The proposed combustion/carbon removal approach allowed stable operation of the ICP even when introducing highly volatile solvents that otherwise would have immediately extinguished the plasma. Analyte signals in halogenated solvents were found to be significantly higher than in non-halogenated ones and non-linear calibration functions were observed for all investigated analytes below 5 mg kg À1. Though a stable operation of the plasma was possible, the analyte signal intensities obtained in water were, depending on the element and the solvent, between 1.5 and 2800 times higher than in halogenated solvents.

“…For liquid sample introduction, coupling of the ETV to the ICP-MS offers several advantages over nebulization (1)(2)(3), including (i) the amount of solution needed for the analysis is very small (5-10 ml), (ii) the significantly improved transport efficiency gives rise to lower detection limits, and (iii) by the use of appropriate heating programs and/or matrix modifiers both spectral and nonspectral interferences can be reduced. Studies reporting on the exploration (4)(5)(6)(7)(8)(9) and exploitation (10)(11)(12)(13)(14)(15) of these characteristics can be widely found in the literature.…”
