Supercritical Extractor with GC-MS

Supercritical Fluid Extraction (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids as the extracting solvent. Carbon dioxide (CO2) is the most used supercritical fluid, sometimes modified by co-solvents such as ethanol or methanol. Extraction conditions for supercritical CO2 are above the critical temperature of 31°C and critical pressure of 74 bar. Propane can also be used as supercritical fluid.


  • The vacuum residue from crude oil distillation can be further separated and analyzed.
  • De-asphaltation of Petroleum could be studied using supercritical propane.
  • Diverse chemical reactions and kinetics (e.g. for biodiesel production) could be studied which uses supercritical fluid as solvent.


  • The reactor is offered on the Autoclave Engineers’ High Temperature, Bolted Closure Laboratory Batch Reactors which is coupled with GC-MS.
  • Currently the GC-MS is connected such that it can analyze the gaseous sample vent out from the reactor.
  • Maximum combination; Pressure = up to 300 bars, Temperature profile = up to 150C.
