Carbon dioxide (CO2) densimeter calibration data

Splitting of the carbon dioxide Raman Fermi diad was measured using three different Raman instruments and various lasers and dispersion gratings. Data were collected at Virginia Tech and at the U.S. Geological Survey in Reston, VA. The purpose of the study was to compare densimeters determined using different analytical methods. The results show that calibrations are instrument and analytical condition dependent, and one should develop a densimeter that is specific to the users instrument and analytical protocols to obtain carbon dioxide pressures based on Raman analysis of bubbles in fluid and melt inclusions.
