Case Study

1,1,3,5,5-Pentaphenyl-1,3,5-Trimethyltrisiloxane Can Be Used as a Pressure Measuring Liquid for Interferometric Micromanometers

Ehlers, Sven, et al. Measurement, 2019, 132, 191-198.

In this study, criteria were established for selecting manometric liquids based on their vapor pressure, density, viscosity, capillarity, and optical characteristics. Seven different types of vacuum oils including carboxylate esters, siloxanes (such as 1,1,3,5,5-pentaphenyl-1,3,5-trimethyltrisiloxane), hydrocarbons and ethers were selected for analysis. The study measured density, thermal expansion coefficient, and viscosity of these liquids at atmospheric pressure near room temperature. From these, three liquids were selected for more detailed investigation. Their density and kinematic viscosity were reassessed with improved accuracy, and additional parameters such as compressibility, density changes with gas saturation, absorption and desorption kinetics, and diffusion coefficients for nitrogen, oxygen, argon, helium, and water were determined. Furthermore, the surface tension and contact angle on PTFE for four oils were measured.
Ultimately, the three liquids identified as the most suitable candidates for a manometric liquid in the new 2 kPa interferometric micromanometer were F02 (1,1,3,5,5-Pentaphenyl-1,3,5-trimethyltrisiloxane), F06 (multi-ring polyphenyl ether), and F07 (synthetic hydrocarbon). Each liquid offers distinct advantages: F02 exhibits the best vapor pressure and wettability; F06 has the lowest nitrogen solubility; and F07 features the lowest density, viscosity, and water solubility.
