ABSTRACT:
A liquid sample is placed in a closed vessel. A thermocouple junction is submerged in the liquid sample. The pressure of the liquid is decreased, or the thermocouple junction is heated, until boiling from the thermocouple junction is detected. The pressure or temperature is then varied until the boiling just ceases. The pressure and temperature at cessation of boiling define the boiling point free of spurious liquid superheating effects.
