Abstract
An integrated mobile phase degassing and blending apparatus for transport of liquid chromatography fluids therethrough includes a component having a first portion and a second portion, with the first portion defining an enclosed degassing chamber, and the second portion including a mobile phase blending device, wherein the degassing chamber and the mobile phase blending device are operably coupled to one another such that the liquid chromatography fluids pass directly into the blending device from the degassing chamber. In a particular embodiment, the degassing chamber is specifically configured to accommodate multiple distinct flexible degassing tubes.
Claims10
An integrated mobile phase degassing and blending apparatus, comprising:
- a component having a first portion and a second portion, said first portion defining an enclosed degassing chamber for degassing mobile phase passing therethrough, said degassing chamber being operably coupled to a vacuum source such that said degassing chamber has a reduced internal pressure, said second portion of said component including a mobile phase blending device, said degassing chamber and said mobile phase blending device being operably coupled to one another such that the mobile phase passes directly into said blending device from said degassing chamber.
An integrated mobile phase degassing and blending apparatus, comprising:
- an enclosed degassing chamber integrally disposed and operably coupled with a blending valve device, said degassing chamber being specifically configured to operably accommodate multiple distinct degassing tubes respectfully transporting distinct mobile phase streams therethrough, said degassing chamber being operably coupled to a vacuum source to obtain a reduced internal pressure within said degassing chamber, said degassing tubes being gas-permeable, liquid-impermeable such that the mobile phase is effectively degassed while passing through said degassing chamber.
