Hexachloroplatinic(iv ) acid (H2PtCl6·6H2O, Nacalai Tesque), palladium(ii ) chloride (PdCl2, Nacalai Tesque), rhodium(iii ) chloride hydrate (RhCl3·3H2O, Aldrich), poly(N-vinyl-2-pyrrolidone) (PVP, K-30, average M.W. = 40 000, Tokyo Kasei Kogyo Co.), ethanol (guaranteed reagent, 99.5%, Nacalai Tesque), and distilled water were used without further purification. Benzophenone ((C6H5)2CO, guaranteed reagent) was used as a photoactivator which was purchased from Nacalai Tesque.
Rhodium
Manufactured by Merck Group
Sourced in Germany
Rhodium is a precious metal used in various laboratory equipment. It is a highly reflective, corrosion-resistant, and durable material. Rhodium is often used as a protective coating or alloying element in laboratory instruments and apparatus to enhance their performance and longevity.

Plasma samples (50µl) were subjected to inductively coupled plasma mass spectrometry, measuring 82Se because of its low background noise. Plasma and Se standards were prepared in 2% nitric acid (HNO3) containing approximately 6 parts per billions rhodium (Aldrich Chemical Company, Inc., Milwaukee, WI) and 0.1% Triton X-100. A set of Se standards was inserted every 10 samples for external drift correction. Seronorm Trace Elements Serum L-1 (SERO, Billingstad, Norway) was used at the beginning and the end of each run to check the accuracy of measurements.

For quantification of the total Hg content by ICP-MS, aliquots of the transfer studies and cellular bioavailability studies were diluted in a solution of 5% HNO3 + 5% HCl (v/v, both suprapur, Merck KGaA). An external calibration (1–150 ng/L; Hg standard for ICP, TraceCERT®, Fluka, Deisenhofen, Germany) was prepared in the same solution. Samples and calibration standards were incubated with rhodium (final concentration 10 ng/L; Merck KGaA, Darmstadt, Germany) as internal standard. A MicroMist nebulizer was used for sample introduction and gas flows were applied as follows: 15 L/min cool gas, 0.9 L/min auxiliary gas and 1 L/min nebulizer gas. The method exhibits a limit of detection of 0.8 ng/L and a limit of quantification of 2.9 ng/L calculated by the calibration method of the German Standard DIN standard 32645 [30 ].

Two hundred µL of blood sample was diluted 1:50 with Millipore water, 20-µL 65% HNO3, and 300-µL Triton X 10%. One hundred µL rhodium 1 mg/L was added as internal standard (Merck, Darmstadt). The final volume was 10 mL. The calibration standards ranged from 20 to 7000 ng/L and comprised 9 doted blood samples as standards including a blank.
Samples were centrifuged for 10 min at 3000 rpm, the sedimented residue was discarded, and the liquid samples were measured on an ICP-MSMS Agilent 8900 (Agilent Technologies, Waldbronn, Germany) on mass 207 in the SQ-He Mode, using Rh 103 in the same mode, as internal standard. The limit of quantification (LOQ) of the method was 0.1 µg/L and therefore sufficiently low for environmental sample analysis. The laboratory successfully participates in international round-robins of the German External Quality Assessment Scheme (G-EQUAS) of the Friedrich-Alexander University of Erlangen-Nuremberg. Control materials were measured with each analytical run as a quality control. Two controls were measured every 10 samples. After 5 samples, a sample blank was measured.

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.
