Development of a Nonisothermal Knudsen Effusion Method and Application to PAH and Cellulose Tar Vapor Pressure Measurement

The Knudsen effusion technique has long been employed as an indirect method for determining the vapor pressures of low-volatility materials. The method is tedious and, if not carefully applied, subject to considerable errors in temperature measurement. It is also desirable to shorten the time of mea...
