Gradient elution in supercritical fluid chromatography

The applicability to supercritical fluid chromatography (SFC) of elution by gradients in eluent composition is demonstrated, using alkanes and diethyl ether as the primary eluent and alcohols, cyclohexane and dioxane as the secondary component. For the separation of styrene oligomers, the combinatio...

Description
Summary:The applicability to supercritical fluid chromatography (SFC) of elution by gradients in eluent composition is demonstrated, using alkanes and diethyl ether as the primary eluent and alcohols, cyclohexane and dioxane as the secondary component. For the separation of styrene oligomers, the combination of an alkane with dioxane turned out to be the most efficient. The SFC apparatus used was a modified high-performance liquid chromatographic instrument.
