Helix: 2 CO2 Separators

Helix: Basic CO2 Extraction System with Two CO2 Separators

The Helix CO2 Extraction System with 2 CO2 separators gives you the opportunity to extract samples normally up to one liter in volume at up to 10,000 psi and up to 240°C and discharge the extract to 2 different separators; cascading in decreasing pressure from separator #1 to separator #2 and then to ambient collection.

  • temperatures to 240°C – no technical limitations because of not having sufficient heat
  • pressure up to 10,000 psi (690 BAR) – get maximum density and solvating power, don’t leave extracts in the pressure vessel
  • holds 24mL to 1L vessels standard;– start with a small sample and scale up—no problem
  • pump flow rates up to 400mL/min - extract quickly and efficiently*
  • fully-adjustable, non-clogging, micrometering valves control flow rate
  • collection into standard glassware, chilled collection to capture volatile compounds, on SPE for further chromatographic separations
  • in-vessel chromatographic capabilities
  • modifier addition capability – extract polar compounds, too
  • multiple flow path – efficiency, efficiency, efficiency
  • extract liquid samples as liquids
  • stirrer capability
  • view cell - capability to look inside of vessel – keep a video record
  • configurations for multiple/varied applications, check applications sections

Helix Supercritical Fluid System with 2 separators
Where this configuration might be used is the extraction of black pepper. Black Pepper contains several distinct components that may be dissolved in supercritical CO2 at 500 bar and 90°C and separated as the pressure is sequentially lowered.

  • A resinous material is collected in separator #1
  • a piperine concentrate in separator #2
  • an essential oil in the final collection container at atmospheric pressure
