I was checking out diamond anvil cells and i have few questions.
I have been on this sites:

http://merkel.zoneo.net/FEM/index.php?lang=en (3)

1.what is max pressure you can make in dac?
2.how can dac works at 100GPa if compressive strength of diamond is (1)8,680-16,53 GPa, (2)43,72GPa ?
3.What determines how much is max dac pressure?

The maximum pressure that can be achieved in a diamond anvil cell (DAC) depends on the type of DAC being used as well as the materials used in its construction. Generally, the highest pressures are achieved with DACs that use two diamonds as their anvils. The highest pressure achieved in such a cell is around 300-400 gigapascals (GPa). The compressive strength of diamond plays an important role in determining the maximum pressure achievable in a DAC. The higher the compressive strength of the diamond, the higher the pressure that can be achieved. Other factors that can affect the maximum pressure achievable in a DAC include the size and shape of the anvils, the type of medium used between the anvils, and the type of pressure-transmitting fluid used. For more detailed information on DACs and how they work, you can refer to the references given in the links provided above.
