Abstract
In a method for measuring the vapor pressure of liquid and solid substances, in which a sample of the substance is arranged in a variable volume of a measuring cell, the measuring cell is gas-tightly closed. The volume of the measuring cell is increased until reaching a measuring volume, and at least one first value of the gas pressure prevailing after the increase in volume is measured. The volume of the measuring cell is additionally reduced until reaching the measuring volume, and at least one second value of the gas pressure prevailing after the reduction of the volume is measured. The vapor pressure is calculated from the at least one first and at least one second measured values.
