Solution Overview
Problem
Current field flow fractionation methods are not scalable for preparative applications, as they are inherently batch processes that struggle with processing gram or kilogram quantities, making them unsuitable for large-scale purification and production of therapeutic doses or bio-nanoparticles.
Innovation Solution
The development of a continuous field flow fractionator system that injects a sample in a continuous flow, establishing an exponential concentration profile and controlling flows through multiple outlets to extract different fractions, allowing for continuous fractionation and scalability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If batch field flow fractionation methods are used, then separation precision is achieved, but productivity and scalability for preparative applications deteriorate
Solution Approach 1:
The patent implements continuous field flow fractionation where the sample is injected continuously rather than in batches, allowing the separation process to operate continuously. This enables gram or kilogram quantities to be processed over time while maintaining separation precision through continuous exponential concentration profile establishment and fraction collection
Solution Approach 2:
The patent divides the continuous sample flow into multiple fractions through multiple outlet ports, with each outlet collecting specific fraction ranges. This segmentation allows different portions of the continuous sample to be separated and collected simultaneously, maintaining precision while enabling scalable processing capacity
2Manufacturing precision
If batch processing is used, then manufacturing precision is maintained, but the ability to process large quantities (gram or kilogram) deteriorates
Solution Approach 1:
The continuous injection mode allows the system to process large quantities of sample continuously over time rather than in discrete batches. The exponential concentration profile is established continuously, enabling gram or kilogram quantities to be fractionated while maintaining precision through continuous operation
Solution Approach 2:
The system dynamically adjusts flow rates and extraction parameters during continuous operation to maintain optimal separation conditions. The computer system controls flow rates through multiple outlets to ensure precise fractionation even as large quantities of sample are processed continuously
3Productivity
If continuous flow injection is implemented, then productivity and scalability improve, but device complexity increases
Solution Approach 1:
The continuous field flow fractionator is designed with multiple outlet ports that can simultaneously collect different fractions, allowing a single device to perform multiple separation functions. This multi-functionality enables continuous processing of large quantities while managing complexity through integrated design
Solution Approach 2:
The computer system provides feedback control by monitoring flow rates and sample conditions, automatically adjusting parameters to maintain optimal separation. This feedback mechanism manages system complexity through automated control rather than manual intervention
