Each MS-spectrum was recorded in duplicate for which 100 µL aliquots of each sample were digested in 1 mL of 16N Nitric Acid (Anachemia Environmental Grade) in clean Teflon digestion vessels. These samples were heated to approximately 120°C overnight until the digestion was complete. The samples were then quantitatively transferred to clean polyethylene sample vials and diluted to 50 mL with 18.2 mega-ohm deionized water. Trace element analysis was performed on a Thermo X-Series II quadrupole ICP-MS run in standard mode with glass concentric nebulizer, Peltier cooled glass impact bead spray chamber, and on-line internal standard addition. A mixture of Rh, In, and Re was used as the internal standard. Calibration standards were prepared from NIST traceable mixed element stock solutions. Instrumental precision and accuracy were determined by six replicate analyses of the Certified Reference Material SLRS-5 (Ottawa River Water, NRCC), these replicates were spread over the course of the analytical run.

For the determination of Ca, Fe, Mg, Mn, P, K, Na, and Zn using PerkinElmer (Shelton, CT, USA) model Optima 3000 Dual View ICP-OES, 0.5 g test portions from ten packets of SRM 3232 were digested in a closed-vessel microwave system using nitric acid. In and Sc were used as internal standards. For ICP-MS determination of As, 0.5 g test portions from six packets of SRM 3232 were digested in a closed-vessel microwave system using nitric acid. Rb and Y were added and the sum of the intensities of ⁸⁵Rb and ⁸⁹Y was used as the internal standard for the determination of arsenic in high resolution mode (R≈10,000) by ThermoFisher Scientific model Element XR sector field ICP-MS. Se was used as the internal standard for the determination of arsenic by ThermoFisher Scientific model XseriesII quadrupole ICP-MS. The instrument was operated in collision cell mode using 7% H₂ in He as a collision gas. For the determination of iodine by ThermoFisher Scientific model X7 ICP-MS, 0.2 g test potions from eight packets of SRM 3232 were digested in a closed-vessel microwave system using ammonium hydroxide. Rh was used as an internal standard. Quantification for all analyses was based on the method of single-point standard addition using the SRM 3100 series single-element standard solutions for calibration.

Quantifying Thallium in Samples via ICP-MS

All standards and samples were analyzed for total Tl content using an X-Series II quadrupole ICP-MS (Thermo Fisher Scientific, Bridgewater, NJ) equipped with a Peltier-cooled spray chamber and an ASX-500 autosampler (Teledyne CETAC Technologies, Omaha, NE). Instrument parameters used on all days of the validation study are shown in Table S1 (Supplemental Information). The ICP-MS was tuned daily by aspiration of a solution containing 10 μg/L indium to maximize signal intensity and stability. The ²⁰⁵Tl signal was measured in all standards and samples as a ratio of the ¹⁴¹Pr IS signal to account for instrument drift. The ratio of Pr signal in each standard and sample to the Pr signal in the initial blank was calculated to adjust the intensity of the Tl signal in each standard and sample, and the adjusted Tl intensity was plotted against standard concentration. Adjusted Tl intensity and concentration were related using a linear least-squares regression to produce the calibration equation. Total Tl in all samples in units of ng Tl/mL extract was calculated against the calibration equation and the final concentration in each sample matrix was calculated using dilution factors arising from the sample digestion process.

Determining Hf/W Ratio in CAI BE

Check if the same lab product or an alternative is used in the 5 most similar protocols

The Hf/W ratio of the CV chondrite refractory inclusion dubbed CAI BE was determined by doping with a mixed ¹⁸⁰Hf-¹⁸⁶W tracer as described in Holst et al. (2013) . A doped 0.3% aliquot of the bulk sample was passed over a cation column (1 mL AG50W-X8) to remove most matrix elements. It was then converted to NO₃⁻ form and fluxed on a hotplate before analysis. The measurements were performed on a ThermoFisher X-series II quadrupole ICPMS. In the same run, we conducted a tracer calibration against Alfa Aesar solution standards of known concentration and isotopic composition to obtain the elemental Hf/W ratio in the mixed tracer. The tracer calibration is necessary as the tracer composition changes with time due to the variable behavior of Hf and W when stored in solution.

DFe and CNFe were determined at the National Oceanography Centre (Southampton) Mass Spectrometer Lab, using a Thermo Scientific XSERIES 2 quadrupole ICP-MS, with Be, In and Re as internal standards. CNFe blanks were 1.2±0.7% of the lowest recorded concentration. DFe blanks were at or below the machine’s detection limit of ~\n1 nM—sample values lower than this were recorded as

Cell-free BAL supernatants were centrifuged at 44,900 × g for 30 min and Zn²⁺ concentrations were determined. Lung, liver, spleen, kidney, heart and brain tissues from mice in each group were stored at −80°C immediately after resection. Tissues were lyophilized for 16 hr at 0.13 mBar and −50°C in a freeze dryer (Labconco Corp., Kansas City, MO) and then weighed. The tissues were digested in a HotBlock™ digestion system (Environmental Express, Mt. Pleasant, SC) at 95-98°C using mixtures of high purity concentrated hydrochloric acid and nitric acid (Fisher Optima® grade) in 1:3 ratio, respectively. Metal analysis of the digested tissues, blood and BAL fluid was performed using inductively coupled plasma mass spectrometer (Xseries 2 quadrupole ICP-MS, Thermo Fisher Scientific Inc., West Palm Beach, FL) with a method detection limit for Zn of less than 1 μg/kg. Each sample was spiked with cobalt as an internal standard at 20 μg/L.

Trace Metal Analysis by ICP-MS

Dissolved (<0.02 µm) and filterable (<0.45 µm) trace metal concentrations were analyzed using a Thermo Scientific X-SERIES 2 quadrupole ICP-MS with a collision-reaction cell at the National Oceanography Centre, Southampton. Berylium, indium and rhenium were used as internal standards to correct for drift and matrix effects, and external calibration solutions (n = 7) matched the concentration range observed in samples. For trace metals presented in this study, precision and accuracy were always within ± 10% of a multi-element standard, prepared from a gravimetrically weighed mix of NIST-traceable SPEX CertiPrep standards. Colloidal-nanoparticulate (0.02-0.45 µm) concentrations were calculated as the difference between 0.45 µm filterable and dissolved size-fractions (Shiller, 2003) (link).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
