As a pressure gauge, Ruby is the most common and wildly used mineral for determining pressure in DAC experiments, but it has difficulty in such an experiment that simultaneously contains high temperature and water. Quartz is a new mineral proposed recently as a pressure gauge and it can be used with the system containing water, however it is limited at the pressure p<2.0 GPa and the temperature T<600 ℃. On the other hand, equation of state (EOS) of material is much reliable for determining the pressure in the experimental studies with DAC, but it is inconvenient and limited by the condition of instrument. For example, EOS of water is useful if the system is aqueous solution and no mineral can be used as a pressure gauge in order to avoid any interaction. Therefore, comments and suggestions have been addressed in this manuscript.
