“…Indeed, this study did not consider the many elements that are present in otoliths at the sub-ppm level (e.g., Cd, Sn, Rb, U), which are probably not detectable in otoliths even with PIXE and LA-ICPMS. Resonance ionization spectroscopy (Arlinghaus et al 1993), synchrotron monochromatized X-rays (Ishikawa et al 1991), and laser-induced fluorescence spectroscopy (Coutant 1990) could conceivably fill this gap, as well as secondary ion mass spectrometry, Fourier transform infrared spectroscopy, micro Raman spectroscopy, and others (Jackson et al 1993;Jambers et al 1995). In general, bulk and (or) solution-based elemental assays such as isotope dilution ICPMS (Fassett and Paulsen 1989), accelerator mass spectrometry (Rucklidge 1995), and neutron activation analysis (Schmitz et al 1991) are capable of better accuracy, precision, and (or) sensitivity than are beam-based assay techniques.…”

The elemental composition of fish otoliths is of considerable interest to those who wish to reconstruct temperature, migration, or environmental histories of individual fish based on assays of the otolith growth sequence. However, reported differences in otolith elemental composition among studies may be due in part to performance differences among four of the most popular instruments for targeted elemental analysis: wavelength-dispersive electron microprobe (WD-EM), energy-dispersive electron microprobe (ED-EM), proton-induced X-ray emission (PIXE), and laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS). To rigorously compare the sensitivity, accuracy, and precision of these four analytical tools, the International Otolith Composition Experiment distributed blind-labelled real and artificial otoliths of known but varied elemental composition to eight laboratories for assay of 10 selected elements. No one instrument type was sensitive to each element, nor was any one instrument preferred for use in all assays. In general however, abundant elements such as Na and K could only be measured accurately with an electron microprobe, while the trace elements required PIXE or LA-ICPMS. Strontium could be measured with considerable accuracy and precision by WD-EM, PIXE, and LA-ICPMS. The presence of significant, and occasionally large, differences among laboratories suggests that comparisons among published studies should be made cautiously and only after appropriate calibration.

“…However, the elemental fingerprints of whole otoliths were far more powerful in distinguishing among the cod stocks than were laser-based assays of the same fish using the otolith nucleus. Technical reasons for the discrepancy included the greater sensitivity and enhanced precision of solution-based ICPMS compared with EA-IGPMS (van Heuzen 1991;Hall 1992;Jackson et al 1993). In addition, the sister study failed to randomize the sample assay sequence (as was done here), which may have contributed artifactually to apparent stock discrimination success.…”

“…The latter constraint can be overcome by insuring that the order of sample assays is statistically blocked, crossed, and balanced with respect to sample site, as was done in this study. However "memory effects", due to transient particle deposition in the transfer tubes (van Heuzen 19911, are more problematic, and undoubtedly contribute to CV's that are somewhat greater than those observed with either conventional ICPMS (Jackson et al 1993) or an electron microprobe. Spatially, the 30-km spot size of the laser cannot compete with the 3-p~m spot size of an electron microprobe (Gunn et d.…”

Trace element incorporation into fish otoliths varies among samples collected at different sites. If otolith elemental composition (the elemental "fingerprint") somehow reflects the characteristics of the ambient water, the elemental fingerprint of the otolith nucleus could serve as a natural marker of fish hatched at different sites. To test this hypothesis, Atlantic cod (Gadus morhua) otoliths collected from five spawning grounds in the northwest Atlantic were tested for differences in elemental and isotopic composition. Laser ablation – inductively coupled plasma mass spectroscopy (LA-ICPMS) was used to assay the concentration of 14 isotopes (nine elements) in otolith nuclei. The sensitivity of the laser ablation system exceeded that of the electron microprobe by 2–4 orders of magnitude, with an average CV of 21% for any given isotope. Most isotopic concentrations were consistent between left and right otoliths of a given fish, and most differed significantly among sample sites; there were no significant differences by age, sex, or fish length. Multivariate analyses of the elemental fingerprints resulted in significant discrimination among sample sites. While the mechanism underlying trace element incorporation into otoliths is still unclear, otolith elemental fingerprinting has the potential to become an effective and accurate means of stock identification.

“…In addition, there is excess acid consumption in conventional sample preparation techniques. [1][2][3][4][5][6] Despite advances in instrumentation and microcomputer technology, many sample preparation practices are based on nineteenth-century technologies. Furthermore, there is a serious contamination risk with these procedures.…”

In order to evaluate the data obtained by atomic emission spectrometric analysis after ultrasonic extraction, destructive analysis of some certified rock samples employing ultrasonic waves was applied to two elements, Na and K, and the recovery rates were defined. The recovery ratio as K1=CULM/CCRM was defined for the ultrasonic leaching method (CULM) and the certified reference materials (CRMs). Another recovery ratio, K 2 was also defined from the results of the conventional dissolution method (CCDM), that is K2 CULM/CCDM. The accuracy and precision of the method were comparable with those of the conventional methods. The obtained recoveries were between 90.0 %< K1, Na<106.1 and 90.0%<K2, Na<103.0 % for Na and 92.3%<K1, K<103.2 and 92.3%<K 2,K < 104.5%for K. It was shown that ultrasonic extraction can be effectively used for analytical sample preparation purposes.
