Finding the most accurate equation of state (EOS) for the calculation of the interrnal pressure of fluid inclusions and their isochores can be a challenge for fluid inclusionists. Based on our comprehensive evaluation of various EOS, we select the most accurate EOS up to date for the fluid systems listed below. Just click the system of your fluid inclusions, you are asked to input some information, such as homogenization temperature, the online program will help you calculate the internal pressure, and then by fllowing the steps, you will be able to calculate isochores.

The program is still under development, your comments or suggestions are welcome, please send e-mails to duanzhenhao@yahoo.com or maoshide@cugb.edu.cn
