“…The column-conditioning step removes any residual acid that remains from the previous sample elution step and ensures that the resin is no longer in the protonated form, which might otherwise reduce retention of the analyte and thereby lessen the sensitivity of the method.

A sensitive flow-injection method with chemiluminescence detection (FI-CL) for the determination of dissolved cobalt in open ocean samples, suitable for shipboard use has been developed. To date, FI methods for dissolved cobalt have been used only in coastal and estuarine waters. Therefore, significant modifications to existing methods were required, including (1) the use of a commercially available iminodiacetate (IDA) resin (Toyopearl AF-chelate 650M) in place of resin immobilized 8-hydroxyquinoline for online preconcentration and matrix removal, (2) the introduction of acidified ammonium acetate (pH 4) as a column-conditioning step before sample loading and rinse steps, and most importantly, (3) UV irradiation of acidified seawater samples to determine total dissolved cobalt, rather than an operationally defined fraction. This method had a detection limit of 4.5 pM (3s of the blank). The accuracy of the method was evaluated by determining total dissolved cobalt in acidified North Pacific deep seawater (1000 m) samples from the Sampling and Analysis of Iron (SAFe) program and NASS-5. The method yields a mean (± SD) value of 40.9 ± 2.6 pM (n = 9), which is in excellent agreement with the SAFe consensus value of 43 ± 4 pM, and 208 ± 30 pM for NASS-5 (certified value 187 ± 51 pM). This study demonstrates that UV irradiation is an essential step for the determination of total dissolved cobalt in seawater by FI-CL. The method was applied to vertical profiles from the Sargasso Sea, indicating that total dissolved cobalt is influenced by both biological and physical processes.

“…Acidified samples were UV-oxidized for 30 min prior to analysis. Trace metals were then concentrated on the resin at the appropriate pH and eluted with 1 M QHNO 3 (Willie et al, 1998;Warnken et al, 2000;Willie et al, 2001;Ndung'u et al, 2003). The filtrates were loaded onto the resin column for 2 min for medium resolution analytes ( 56 Fe, 59 Co, 63 Cu, and 66 Zn) at a pH of 5.5 with an ammonium acetate buffer and 30 s for low resolution analytes ( 55 Mn, 111 Cd) at a pH of 8.9 with an ammonium chloride buffer in separate analyses (Hurst and Bruland, 2007).…”

“…Currently, isotope dilution inductively coupled plasma mass spectrometry appears to be a method of choice and several successful reports of its use for the accurate and precise characterization for otolith material have appeared. [7][8][9][10][11] However, research in this area has generally been impeded by a lack of certified reference materials for analytical quality assurance. The National Institute for Environmental Studies (NIES), Environment Agency of Japan, recently released a fish otolith reference material certified for Na, Mg, K, Sr and Ba for this purpose, 9 but there remains a need not only for complementary materials, but for materials which are certified for additional trace heavy metals that can serve as additional markers to extend the usefulness of otolith composition for fisheries studies.…”

The material was prepared from 4.5 kg of dried saggital otolith harvested from the red snapper (Lutjanus campechanus), ball milled and sieved to o200 mesh, homogenized, irradiated, bottled into 1 g aliquots and certified for major, minor and trace element composition using inductively coupled plasma mass spectrometry (ICP-MS), isotope dilution-ICP-MS, neutron activation, ICP-optical emission spectrometry and X-ray fluorescence. Several laboratories participated in this activity, providing for a robust estimate of each measurand.
