How the Vapour Pressure Analyser works

Variable piston expansion enables vapour pressure testing to a wide range of temperatures and vapour-liquid ratios.

Product flows into a measuring cell, where resistance thermometers enable the cell and sample temperature to be accurately controlled. A small, defined volume of the sample is held in place by a piston, which utilises icon’s laser controlled liquid-vapour ratio measurement technology for exceptional accuracy and superior repeatability.

Once equilibrium is established, the absolute pressure inside the cell is converted into actual vapour pressure as required by the test method being emulated. This enables the vapour pressure to be measured in accordance with various test models and the most up-to-date standards.
