An Agilent 8800 ICP-MS/MS instrument (Agilent Technologies, Tokyo, Japan) with oxygen as reaction gas was used to determine the content of the respective elements. The ICP-MS parameters were tuned on a daily based to achieve high sensitivity. The ICP-MS was equipped with a MicroMist nebulizer with a sample uptake rate of ∼0.25 ml·min−1 and standard nickel cones. The instrument was coupled to an Agilent 1260 Infinity Bio-Inert HPLC system (Agilent Technologies, Waldbronn, Germany). The Agilent MassHunter software package (Workstation Software, Version C.01.06, 2019) was used for data evaluation. The instrumental parameters for the ICP-MS measurements are summarized in Table 2 .

An Agilent 8800 ICP-MS/MS instrument (Agilent Technologies, Tokyo, Japan) with oxygen as reaction gas was used to determine the sulfur content. The ICP-MS parameters were tuned on a daily base to achieve high sensitivity. The ICP-MS was equipped with a MicroMist nebulizer with a sample uptake rate of ∼ 0.25 mL min−1 and standard nickel cones. All sulfur isotopes were measured using oxygen as reaction gas (flow rate = 0.32 mL min−1) with mass selection steps on both quadrupoles. The following isotopes were monitored with a respective integration time of 0.1 s: 32S16O+, 33S16O+, 34S16O+, and 36S16O+. The instrument was coupled to an Agilent 1260 Infinity Bio-Inert HPLC system (Agilent Technologies, Waldbronn, Germany). The Agilent MassHunter software package (Workstation Software, Version C.01.03, 2016) was used for data evaluation. The instrumental parameters for the ICP-MS measurements are summarized in Table 1 .

RP-ICP-MS measurements were performed on an Agilent 1260 Infinity Bio-inert HPLC system (Agilent Technologies, Waldbronn, Germany) hyphenated to an Agilent 8800 ICP-MS/MS instrument (Agilent Technologies, Tokyo, Japan). Chromatographic separations were performed using an Atlantis T3 C18 analytical column (150 mm L × 2.1 mm i.d., 3 μm dp, 100 Å pore size) equipped with an Atlantis T3 guard column (20 mm L × 2.1 mm i.d., 3 μm dp) from Waters (Milford, USA). Chromatographic conditions are summarized in Table S2.† The ICP-MS/MS was equipped with a torch with 1.5 mm inner diameter, platinum cones and the brass-based lens system in order to withstand the high organic solvent load. Oxygen was introduced as the option gas and admixed with the aerosol before entering the ICP-MS to avoid carbon deposition on the cones. Data processing was performed with the Agilent MassHunter software package (Workstation Software, Version C.01.03, 2016). The ICP-MS operation parameters and chromatographic conditions used are summarized in Tables S1 and S2,† respectively. Samples were measured in triplicates and an aqueous solution of complex 3 (50 μM) was measured after every third sample as quality control.
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.
