Extraction & Fractionation

Our Process

Extraction and fractionation is the broadest application of liquid or supercritical CO₂ and many commercial processes already exist at large scale.

Our equipment allows trials to be carried out on as little as 5g of material through to intermediate laboratory and pilot scale. Extraction can be carried out using CO₂ in a liquid or supercritical state and the choice largely depends on the solubility of the molecules to be extracted.

Liquid CO₂ is significantly less polar than supercritical CO₂ and is more applicable to small, non-polar molecules. In the supercritical state, CO₂ is a highly tunable solvent and the manipulation of temperature and pressure allows selective extraction of a wide range of molecules.

Extraction & Fractionation

Our Process

We have expertise across a wide range of applications of the use of as a solvent including:

Plant derived pharmaceutical and nutraceutical molecules

Pigments from plants and algae

Biosurfactants from fermentation processes

We are setting a pharmaceutical standard for natural product extraction which will be made available to regulators.
