CO2 chromatography has the combined benefits of a liquid to dissolve the medium matrix and also an inert gas to push material through filters and media. Typically, eluent strength is increased by using a polar co-solvent such as methanol, possibly with a weak acid or base at low concentrations ~1%. The solvent strength of CO2 can be increased by increasing density or using a polar co-solvent, however in doing so the fraction of co-solvent takes over the CO2 as the mobile phase. Co-solvents are typically simple alcohols like methanol, ethanol, or isopropyl alcohol. Especially for food-grade materials, the selected co-solvent should be ethanol or ethyl acetate, both of which are generally recognized as safe for food production. The LB-1 works by condensing the intake supply of CO2 gas into a heavy dense cold liquid which fills the process vessel. With temperature control and back pressure regulation, material in the process vessel is pushed through media of your choosing, a tri-fold filter gasket, and two in-line filters (various micron sizes available) achieve a wide range of capabilities in isolating and filtering specific components. The filtered material accumulates in the collection vessel as the CO2 passes back into a gas leaving the heavy botanical mass at the bottom to be collected.
