Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing analytical systems face challenges in efficiently analyzing solid samples that are poorly soluble or require external stressors, leading to costly and time-intensive experimentation, and there is a need for high-throughput analysis of liquid samples without contamination or clogging.
Innovation Solution
The use of filter inserts within sample vials that allow for the dissolution of solid samples in solvent, enabling direct analysis by automated systems, with features like hydrophobic or hydrophilic materials to selectively filter compounds and prevent contamination, and integration with analytical devices for efficient sample extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If solid samples are analyzed directly without complete dissolution, then analysis time is reduced, but analysis accuracy deteriorates due to incomplete solubilization
Solution Approach 1:
The filter insert is placed in the vial before sample dissolution, performing preliminary filtration preparation. This allows solid samples to be dissolved and filtered simultaneously during the automated analysis process, eliminating the need for separate filtration steps and enabling complete solubilization without extending analysis time.
Solution Approach 2:
The filter insert acts as an intermediary component between the solid sample and the analytical system. It mediates the dissolution process by providing a filtration interface that allows complete solubilization of solid samples while preventing undissolved particles from reaching the analytical system, thus maintaining both analysis speed and accuracy.
2Reliability
If filter inserts are added to sample vials, then sample filtration and contamination prevention are improved, but device complexity increases
Solution Approach 1:
The filter insert combines multiple functions into a single component: filtration, contamination prevention, and automated sample extraction interface. By merging these functions into one integrated device that fits standard vial configurations, the system achieves improved reliability without proportionally increasing complexity.
Solution Approach 2:
The filter insert is designed with universal compatibility with standard sample vials and automated analysis systems. Its multi-functional design allows it to serve as a filtration barrier, contamination preventor, and sample extraction interface simultaneously, reducing the need for additional specialized components.
3Manufacturing precision
If manual sample preparation processes are used for solid samples, then complete dissolution can be achieved, but productivity decreases due to time-intensive experimentation
Solution Approach 1:
The filter insert enables the sample preparation system to serve itself by providing automated filtration and extraction capabilities. Solid samples dissolve completely during the automated process without requiring manual intervention, and the filter insert automatically prevents particulate contamination, allowing high-throughput analysis with complete dissolution.
Solution Approach 2:
The filter insert replaces manual mechanical filtration and sample transfer operations with an automated system. The insert's design allows automated syringes or dispensing mechanisms to extract filtered sample solutions directly, eliminating the need for manual filtration and transfer steps while maintaining complete dissolution.
