Dispersive Pipette Tip Baffle System for SPE Mixing

The patent removes the intermediate porous barrier from the system entirely. Instead of using a barrier to force mixing, the invention relies on the natural dispersive properties of the sorbent material itself, which automatically mixes with the sample solution as it passes through the tip without requiring additional components that create back pressure.

The patent eliminates the need for an intermediate barrier by using the sorbent material as its own mediator. The sorbent's dispersive nature allows it to mix with the solution without requiring a separate structural element, thereby avoiding the back pressure and solution losses associated with barriers.

The patent removes the intermediate porous barrier that causes solution losses. By eliminating this component, the system achieves the same mixing efficiency through the inherent dispersive properties of the sorbent, preventing solution from being trapped by the barrier while maintaining effective extraction.

The sorbent material serves as its own mixing mediator without requiring a separate barrier. This eliminates the interface where solution losses occur, as the sorbent disperses naturally within the solution flow without creating a trapping effect that would reduce recovery.

The patent employs the self-dispersing property of the sorbent material itself to achieve consistent mixing. The sorbent's inherent characteristics allow it to automatically mix with the sample solution as it passes through the narrow tip, eliminating the need for external mixing mechanisms and ensuring reproducible results.

The patent optimizes the physical parameters of the sorbent material (such as particle size, shape, and surface properties) to enhance its dispersive properties. These parameter changes enable the sorbent to consistently mix with the solution even in narrow tip configurations, maintaining both efficiency and reproducibility.
