Labhut - HPLC Solvent Degasser

It is important to degas solvents in HPLC, to reduce bubble formation when solvents are mixed and also to increase sensitivity and reduce baseline noise, particularly at low UV wavelengths. Although this can be done by bubbling helium through the solvents, this is expensive and results in the need to check and change cylinders. Helium degassing can also introduce unwanted environmental pollution into the laboratory atmosphere.

On-line degassing has been shown to be the more effective at removing dissolved gas from mobile phases than sonication or helium-sparging. Up to five solvent lines can be degassed simultaneously by one unit. The extremely low volume of each Teflon® AF channel (480 µl) offers very quickly equilibration and very short start-up times. 

Key benefits: 

  • Improves baseline stability and reduces noise
  • Improves pump performance — fewer bubbles, less cavitation
  • Improves laboratory safety — no escape of solvent vapours to the atmosphere
  • Prevents bubble formation in detectors and solvent mixing systems
  • Does not cause mixed solvent depletion
  • Uses only mains power — no need for high pressure gas cylinders
