Supercritical Fluid Chromatography (SFC)

When a material is in a state that the temperature and the pressure exceed the critical point, it becomes a supercritical fluid. In this phase, the density of gas and liquid becomes same. Super critical fluid is a special phase which has either gas and liquid character but different from these.

• Low viscosity : Quick separation with low pressure drop
• High diffusivity : High unit productivity
• Low solvent consumption : Environmental friendly. CO2 can be recycled.
• Acidic behavior of CO2 : No additive such as TFA is required.
