Distilled water was further purified by passing it through a mixed bed of ion-exchanger (R3-83002, M3-83006, Bioblock Scientific, Illkirch, France) and activated carbon (Bioblock Scientific ORC-83005) and was de-oxygenated by CO2- and O2-free argon (Sigma Oxiclear cartridge) before use. All the stock solutions were prepared in spectroscopic grade dimethylsulfoxide (DMSO, Bioreagent for Molecular Biology, >>99.9%, Sigma) by weighing solid products using a XA105 Dual Range (0.01/0.1 mg–41/120 g) balance Mettler Toledo (Viroflay, France) and the complete dissolution was achieved using an ultrasonic bath. The ionic strength was maintained at 0.1 M with sodium perchlorate (NaClO4.H2O, Merck, p.a.), and all measurements were carried out at 25.0 ± 0.2 °C. CAUTION! Perchlorate salts combined with organic ligands are potentially explosive and should be handled in small quantities and with the adequate precautions [61 ].
Oxiclear cartridge
Manufactured by Merck Group
Sourced in France
The Oxiclear cartridge is a laboratory equipment product designed for the removal of dissolved oxygen from various liquid samples. It functions as a deoxygenation device, utilizing a porous membrane to facilitate the extraction of oxygen from the target liquid. The core function of this product is to provide a controlled and efficient means of reducing dissolved oxygen levels in research, analytical, or industrial applications.

Distilled water was purified by passing it through a mixed bed of ion-exchanger (Bioblock Scientific R3-83002, M3-83006) and activated carbon (Bioblock Scientific ORC-83005) and was de-oxygenated by CO 2 -and O 2 -free argon (Sigma Oxiclear cartridge) before use. All stock solutions were prepared by weighing solid products on an AG 245 Mettler Toledo analytical balance (precision 0.01 mg). The ionic strength was maintained at 0.100(8) M (ESI i ) with sodium chloride (NaCl, Carlo-Erba-SDS Phar. Eur. 99-100.5%), and all measurements were carried out at 25.0(2) °C. The metal stock solutions (∼5-6 × 10 -2 M) were freshly prepared by the dissolution of appropriate amounts of the corresponding solid perchlorate salts in water saturated with argon. Copper(II) perchlorate (Cu(ClO 4 ) 2 •6H 2 O, Fluka, purum p.a., 99.3%) is a commercial product, which was used without further purification. The metal contents of the solutions were determined according to the classical colorimetric titrations. 35 Caution! Perchlorate salts combined with organic ligands are potentially explosive and should be handled in small quantities and with adequate precautions. 36
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.
