From: Onboard experiment investigating metal leaching of fresh hydrothermal sulfide cores into seawater
Schematic of the experimental set up. The ground sulfide sample (3 g) was placed with the artificial seawater (150 mL) in the cylindrical acrylic vessel (250 mL), and then the vessel was tightly closed with atmospheric air or N2 gas. The mixture was stirred with the PTFE magnetic stirring bar, and the temperature was kept at 5 °C or 20 °C in the water bath. The samples solution was collected with disposable syringe from the sampling port. Sampling from anoxic systems was conducted inside the N2 chamber
