“…11 Dependence on the chloride concentration of a NaCl solution of lead species discrimination for inorganic Pb 2+ and Me 3 Pb + (Pb concentration of both solutions is 12 ng Pb mL -1 ) [50] Fig. 12 Dependence on the concentration of chloride in different aquatic systems of the degree of transformation of MeHg + into elemental mercury during ethylation with NaBEt 4 (for reference, 18,000 µg mL -1 is the average concentration of chloride in ocean water) [43] ICP-IDMS were identical within the given standard deviations for both derivatization processes (3.8±0.1 pg mL -1 and 3.6±0.1 pg mL -1 , respectively, for three parallel analyses each). This means that the described CGC-ICP-IDMS method is independent of possible species transformations, because the isotope-dilution step occurred before species conversion during derivatization.…”

“…Corrections can be made for mass bias in ICP-MS. Although in recent years ICP-IDMS has most often been applied during certification campaigns or in connection with analytical quality assurance [10,11], an increasing number of routine analytical problems, such as the determination of lanthanides and actinides in fission products or of heavy metals in plastic materials, have also been solved by ICP-IDMS [12,13]. The multi-element capability, the usually simpler sample preparation compared with TI-IDMS, and the resulting higher sample throughput are the major reasons why ICP-MS is now the preferred analytical method for trace-element determination by IDMS.…”

This critical review discusses the conditions under which inductively coupled plasma-isotope dilution mass spectrometry (ICP-IDMS) is suitable as a routine method for trace element and element-speciation analysis. It can, in general, be concluded that ICP-IDMS has high potential for routine analysis of trace elements if the accuracy of results is of predominant analytical importance. Hyphenated techniques with ICP-IDMS suffer both from lack of commercially available isotope-labeled spike compounds for species-specific isotope dilution and from the more complicated system set-up required for species-unspecific ICP-IDMS analysis. Coupling of gas or liquid chromatography with species-specific ICP-IDMS, however, enables validation of analytical methods involving species transformations which cannot easily be performed by other methods. The potential and limitations of ICP-IDMS are demonstrated by recently published results and by some unpublished investigations by our group. It has been shown that possible loss of silicon as volatile SiF4 during decomposition of a sample by use of hydrofluoric acid has no effect on trace silicon determination if the isotope-dilution step occurs during digestion in a closed system. For powder samples, laser ablation ICP-IDMS can be applied with an accuracy comparable with that only available from matrix-matched standardization, whereas the accuracy of electrothermal vaporization ICP-IDMS was strongly dependent on the element determined. The significance of easy synthesis of isotope-labeled spike compounds for species-specific ICP-IDMS is demonstrated for monomethylmercury and Cr(VI). Isotope-exchange reactions between different element species can prevent the successful application of ICP-IDMS, as is shown for iodinated hydrocarbons. It is also shown for monomethylmercury that species transformations during sample-pretreatment steps can be followed by species-specific ICP-IDMS without loss of accuracy. A relatively simple and time-efficient procedure for determination of monomethylmercury in environmental and biological samples is discussed. The method, which entails a rapid microwave-assisted isotope dilution step and in-situ extraction of the derivatized species, has good potential for routine application in the future.

“…In this context, the work by Perna and co-workers [63] is worth mentioning. The authors described a procedure for the simultaneous separation and determination of lanthanides and actinides (viz., Pu, Np, U, Am and Cm) in sediment and spent nuclear fuel samples and based on the usage of a mixed-bed anionic/cationic chromatographic column (CS5A, Dionex Pu(IV) eluted much later and after U(VI).…”

A number of analytical methods have been developed in the past decades for environmental monitoring of plutonium (Pu) isotopes around nuclear facilities, emergency preparedness as well as for risk assessment of contaminated areas resulting from nuclear weapon tests, nuclear accidents, and the discharge of nuclear waste. This article summarizes and critically compares recently reported methods for determination of Pu isotopes in waters and environmental solid substrates, in which sample pre-treatment is imperative for separation of the target species from matrix ingredients and/or potentially interfering radionuclides prior to detection by radiometric or mass spectrometric detection techniques. Also discussed, via representative examples, is the automation of the entire analytical protocol by on-line extraction chromatography and ion exchange chromatography using flow injection (FI) or sequential injection (SI) approaches.

“…Nowadays, stationary phases having both cation and anion exchange capacities are found to be more useful in separating heavy and transition metal ions [29] because the separation is controlled by the concentrations of free metal ions and the various insitu metal complexes formed, which are in an equilibrium with each other [30]. One such mixed ion exchanger namely Ion Pac CS5A has been widely used for the separation of lanthanides and transition metal cations in several matrices [31][32][33].…”

Retention behavior of U(VI) and Th(IV) as their 2,6-pyridine dicarboxylic acid (PDCA) complexes on reversed phase and ion exchange (cation, anion and mixed ion exchange) columns was studied and based on the results, a simple ion chromatography method for the determination of trace level thorium in uranium oxide using 0.075 mM 2,6-pyridine dicarboxylic acid (PDCA) and 1 M KNO 3 in 1.2 M HNO 3 as eluent (flow rate 1 mL/min) was proposed. The advantage of the developed method is that the separation of uranium matrix is not required prior to the ion chromatographic determination of trace Th. Separation was carried out on a mixed ion exchange stationary phase and a 10 −4 M arsenazo (III) solution was used as post column reagent for detecting the separated metal ions. The separation of Th from uranium using PDCA in the present investigation is attributed through cation exchange mechanism. A calibration plot was constructed by following the standard addition method over the concentration range of 0.25 to 10 ppm of Th in the presence of uranium matrix, which resulted in a linear regression coefficient of 0.9978. The precision of the method was better than 5% and the LOD for Th was found to be 0.1 ppm (S/N = 3). The method has been validated by comparing the results with the results obtained from ICP-MS analysis where the Th is separated from the uranium matrix. The proposed method is simple, rapid, accurate and cost effective compared to techniques like ICP-MS or ICP-AES and is suitable for the routine kind of analysis.
