Vapor pressure for physical chemistry testing
Vapor Pressure for Physical Chemistry Testing establishes the saturation pressure above a solid or liquid substance at various temperatures (in Kelvin). The OECD 104 guidelines incorporate eight methods to measure the vapor pressure (in Pascal) of a test substance: dynamic method (Cottrell’s method), static method, isoteniscope method, effusion methods (vapor pressure balance/Knudsen cell/isothermal thermogravimetry), gas saturation method and spinning rotor method. At least two temperatures should be used to determine the vapor pressure for any method.
