Physico-chemical Properties Measurements

You have the products and need physico-chemical characterization for regulatory or process purpose; in its laboratories, Processium has an expertise for the measurement of these properties and is able to develop reliable measurement methodologies to provide reproducible results on miscellaneous physico-chemical properties.

Moreover, Processium is able to provide process expertise around these measurements.

Regulatory issues:

  • Melting point
  • Boiling point
  • Vapour pressure
  • Density
  • Surface tension
  • Water Solubility
  • Octanol-water partition coefficient
  • Flash point
  • Auto-ignition temperature

Process equipment sizing:

  • Melting and boiling points
  • Heat of phase transition
  • Vapour pressure
  • Density
  • Surface or interfacial tension
  • Viscosity, rheological behaviour
  • Heat capacity
  • Thermal conductivity
  • Solubility
  • Solvent-water partition coefficient
  • Specific surface
  • Particle size distribution

Processium can also perform stability test on various type of products with dedicated methodologies adapted to each specific need.

Processium also develops specific devices to be able to study ageing of your products together with the identification and quantification of decomposition by-products. This method can be adapted for either static or dynamic mode should you need to simulate life cycle of your products. Same devices can be also used to study corrosion aspects linked to the use of your products.
