Elemental standards of mercury, selenium, and sodium were prepared by slow evaporation at room temperature of a drop of standard solutions of Hg, Se and Na in HNO3 at a 1000 µg/ml concentration (PlasmaCAL, SPC Science, Canada) on a silicon wafer.
Nanocrystalline HgSe was synthesised following the method described by Kristl and Drofenik 25 (link) by the reaction of mercury nitrate and selenium powder. Briefly, 0.474 g (0.006 mol) of selenium powder (99+ %, Alfa Aesar) was dissolved in 50 mL of 5M NaOH solution, assisted with sonication, and mixed with a solution of 1.713 g (0.005 mol) Hg(NO3)2.H2O (99.99+ %, Sigma Aldrich, UK) dissolved in 0.1 M EDTA. The molar ratio of 1:1.2 (Hg:Se) was advised as an alternative to performing the reaction under nitrogen flow. The mixture was sonicated at room temperature as the addition of the mercury solution to the alkaline selenium solution occurred, and after 15 minutes of sonication the reaction was continued on a hot plate at approximately 80 °C for 30 minutes. The solution was then cooled and washed with EDTA to remove cations including additional Hg 2+ , water and ethanol. The solution was deposited on a silicon wafer and evaporated.

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.
