Diamond-anvil cell for single-crystal x-ray diffraction studies to pressures in excess of 10 GPa

A new diamond-anvil cell for single-crystal x-ray diffraction structural studies is presented. By including a simple mechanism for adjusting the parallelism of the opposing diamond culets, the stability of the gasket is maintained to higher pressures than was achieved in earlier cells of a similar two-platen design. Equipped with 600 mu m culet diamond anvils, the cell has been tested to a pressure of 25 GPa and has been used successfully for equation-of-state measurements and crystal structure determinations to 10 GPa.
