23. At very high pressure around 100 GPa, the pressure gradient becomes more remarkable in the sample chamber. We estimated the pressure at the sample point, using the first order diamond-Raman signal simultaneously obtained on the Raman measurements of the sample. The pressure induced shift of the diamond signal was, in advance, calibrated with ruby fluorescence frequency.
