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.
