“…Thus, this technique has gained popularity recently for the determination of trace elements and/or their isotope ratios in biological fluids. [6][7][8][9][10][11][12][13][14] Detection limits in the range 12 to 100 pg ml 21 for V in biological fluids have been reported using HR-ICP-MS. 9,10,12,14 In 2001, ThermoFinnigan released software, version 2.1, highlighting new mass offset and lock mass features, which permit correction for mass shift (due to hysteresis within the magnet material) and mass drift (due mostly to thermal effects) previously observed with both their Element 1 and Element 2 HR-ICP-MS insturments. These improvements not only eliminate the need for repeat mass calibrations during daily operation, especially at medium and high resolution, but also provide more stable instrument performance, resulting an improved accuracy and precision of analytical results.…”

Samples were diluted 20-fold in 0.3% HNO 3 . Spectral interference from 35 Cl 16 O 1 , present in urine or serum matrices, was completely resolved from the vanadium major isotope of 51 V 1 at medium resolution of 4000. Quantitation of V in urine and serum was achieved by the method of additions using standards prepared in a pooled urine or serum sample. Mass offset and lock mass ( 40 Ar 16 O 1 ) options were employed for more accurate and precise results. Better than 2.0% RSD was obtained with a 200 pg ml 21 V spike added to a 20-fold diluted urine or serum matrix, reflecting one day stability. Vanadium concentrations in the range of v10 to 1500 pg ml 21 and v10 to 760 pg ml 21 were determined in the urine and serum samples, respectively. Good day-to-day precision of less than 4.0% RSD was typical for both sample matrices. Spike recoveries of 99 ¡ 2 and 98 ¡ 3% (one standard deviation, n~3) were obtained in the urine and serum, respectively. An in-house CRM (SLRS-4: river water) was analyzed daily, yielding a V concentration of 0.337 ¡ 0.010 ng ml 21 (one standard deviati...

We present an apparatus and procedure for culturing deep‐sea (i.e., bathyal) benthic foraminifera under physicochemically constrained conditions. A 1600‐L recirculating culture system was constructed to contribute negligible trace metal contamination; the system was housed in an environmental room maintained near in situ temperatures but at atmospheric pressure. Peristaltic pumps continuously circulated 3 mL seawater min−1 from the reservoir to 9 to 12 culture chambers. A 2‐mm‐thick layer of high‐purity clay‐sized silica substrate was used to minimize the impact of sedimentary microhabitats. Physicochemical parameters (salinity, alkalinity, pH, temperature) varied <2% throughout two culture experiments. Trace metal concentrations were initially set near open‐ocean values and remained constant (i.e., within our analytical precision) during the experiments. Culture seawater was equilibrated with atmospheric CO2, thus dissolved inorganic carbon δ13C varied ~1‰ over the course of each experiment, reflecting the seasonal atmospheric CO2 isotopic variation. Culture seawater δ18O varied ~0.2‰. Each culture chamber was inoculated with as many as 100 foraminifers of single or multiple species. Pre‐existing foraminiferal calcite was identified by fluorescent labeling prior to specimen introduction into culture. The cultures remained viable for >200 d in each experiment and produced up to 2,800 individuals per culture. The growth and reproduction of benthic foraminifera in a physicochemically constrained culture provide a new method for the experimentation and validation of geochemical proxies.

“…Many instrumental analytical methods such as atomic absorption spectrometry (AAS), inductively-coupledplasma optical emission spectrometry (ICP-OES) and inductively-coupled-plasma mass spectrometry (ICP-MS) are used routinely for copper analysis [4]- [6]. These laboratory-based methods have good precision, high sensitivity and low detection limits.…”

Based on poly(vinyl chloride) membranes, a novel miniaturized screen-printed all-solid-state copper(II)-selective electrode has been developed for applications in environmental monitoring. Performance and applicability of the ion-selective electrode (ISE) have been proved by potentiometric investigations. Conducting polymers were used as intermediate layers and as solid contacts between the ion-selective membrane and the graphite transducer. The ion-complexing reagent 2-mercapto-benzoxazole was incorporated into poly(vinyl chloride) membranes. In the concentration range 10 −6 -10 −2 mol/L, the ISE exhibited a linear Nernstian potential response to copper(II) with an average slope value of 28 mV/decade. The detection limit was 3 × 10 −7 mol/L. The electrode exhibits a short response time (<10 s) and can be used in the range of pH = 3 -7. Selectivity coefficents against certain interfering ions are investigated. The life time of the electrode under laboratory conditions was approximately 12-month. The electrode was applied in the investigation of different aqueous environmental samples and the electrode characteristics were described. The copper(II) ASS electrode has also successfully been used in potentiometric, complexometric titrations with ethylenediaminetetraacetic acid.
