摘要：

The vapour pressure of thermally stable substances can be determined easily at ambient pressure using the evaporation rate method. It is possible to measure the evaporation by thermogravimetry in the temperature range from 30 degrees C to 800 degrees C. Vapour pressures as low as 10(-10) Pa (10(-12) mbar) can be determined with excellent reproducibility.
