The separation of blends of styrene-butadiene rubber and butyl rubber is accomplished by liquid chromatography at the critical point of adsorption. Using a non-polar stationary phase and methyl ethyl ketone-cyclohexane as the eluent, the critical point of adsorption of polybutadiene is established.
A phase separator is described that is suitable for post-column HPLC applications. It operates with commonly used HPLC eluents and immiscible organic solvents as long as the two phases remain immiscible. It is compatible with gradient elution systems. Separation efficiency is routinely better than 0
