Why Solvent Filter/Degassers Matter?

Why change another Mobile Phase or new column, Got a noisy baselines.

Why Solvent Filter/Degassers Matters? ------ is a high-efficiency in-line system that is designed to remove dissolved gases from a solvent, then the mobile phase is withdrawn from the solvent reservoir and the degassed liquid is delivered to the pump.
  • Degas eluents as particulates are removed
  • Eliminate spurious peaks caused by outgassing in detectors
  • Eliminate pump downtime caused by air locks and particulates in check valves
  • Decrease piston wear; increase column life
  • Filter safety into plastic-coated or heavy-walled solvent reservoirs
If the on-line degassers work 120% well, then need to clean/replace the Solvent Filter.

However, Do you still remember how to clean that?

Oh......Now I recalled some tough experiences in 3-years-Yellow Jackets Life. At 2005, made "a big mistake"-- put the Solvent Filter in the Ultra- Sonicator with MeOH. The Agilent Solvent Filter is made of glass, then the porous structure on the glass was damaged.
