Abstract
Official abstract text for this publication.
A solvent mixing system includes a mixing tee, a centrifugal mixing path, and a low frequency blending mixer. The mixing tee has at least two solvent input ports and a solvent output port in fluid communication with one another. The centrifugal mixing path has a mixing path inlet in fluid communication with the solvent output port of the mixing tee. The centrifugal mixing path includes at least one coiled segment between the mixing path inlet and a mixing path outlet. The low frequency blending mixer is in fluid communication with the outlet of the centrifugal mixing path.
First claim
Opening claim text (preview).
What is claimed is: 1. A solvent mixing system comprising: a mixing tee having at least two solvent input ports and a solvent output port in fluid communication with one another; a centrifugal mixing path having a mixing path inlet in fluid communication with the solvent output port of the mixing tee, the centrifugal mixing path including at least one coiled segment between the mixing path inlet and a mixing path outlet; and a low frequency blending mixer in fluid communication with the outlet of the centrifugal mixing path, wherein the low frequency blending mixer is a single inlet mixer and comprises: a mixer input port in fluid communication with the outlet of the centrifugal mixing path; a first filter/retainer located downstream of the mixer input port; a mixing chamber; and a second filter/retainer located downstream of the mixing chamber. 2. The solvent mixing system of claim 1 , wherein the mixing tee has an internal mixing volume of about 0.045 uL. 3. The solvent mixing system of claim 1 , wherein the mixing tee is a low volume first in first out (FIFO) mixing point. 4. The solvent mixing system of claim 1 , wherein the mixing tee eliminates stratification of at least two solvent flow streams. 5. The solvent mixing system of claim 1 , wherein the centrifugal mixing path is contoured and shaped to impart a centrifugal force to a high velocity solvent mixture passing between the mixing path inlet and the mixing path outlet at a velocity between about 150 to 17,000 inch/min. 6. The solvent mixing system of claim 1 , wherein the centrifugal mixing path has an inner diameter between about 0.0005 to 0.090 inches. 7. The solvent mixing system of claim 1 , wherein the mixing chamber is a bead packed mixing chamber. 8. The solvent mixing system of claim 1 , wherein the mixing chamber is a diffusion bonded mixing chamber.
