saturated vapor pressure analysis

When a material is heated in a vacuum at a steady heating rate, the weight of the material decreases. With the weight loss caused by vaporing and the change of temperatuure, thermogravimetric curve is obtained and then able to calculate saturated vapor pressure and evaporation rate.
