Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for analyzing low-molecular-weight compounds with specific functional groups, such as thiol compounds, face challenges in distinguishing between compounds with similar functional groups due to low specificity of detection reagents and require complex procedures like reduction reactions and HPLC, leading to insufficient separation and increased operational complexity.
Innovation Solution
An analysis apparatus with multiple flow paths and detection units using detection reagents with varying reactivities to react with specific functional groups, allowing for simultaneous reaction and differentiation of compounds based on signal patterns emitted, enabling efficient analysis without extensive separation processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple detection reagents with different reactivities are used simultaneously, then measurement precision is improved by generating distinct signal patterns for differentiation, but device complexity increases due to multiple flow paths and detection units
Solution Approach 1:
The analysis apparatus is divided into multiple independent detection units, each containing a specific detection reagent. Each detection unit processes samples separately through dedicated flow paths, allowing simultaneous reactions with different reagents while maintaining organized structure and enabling parallel processing of multiple compounds
Solution Approach 2:
The apparatus is designed to handle multiple types of measurement objects with the same functional group using a universal platform. The same basic structure (addition unit, flow paths, detection units) can analyze different compounds (e.g., cysteine, homocysteine, glutathione) by simply changing the detection reagents, providing multi-functionality without requiring separate analysis systems for each compound
2Measurement precision
If complex separation processes like HPLC and reduction reactions are performed, then measurement precision is improved by separating compounds, but productivity decreases due to increased number of operation steps
Solution Approach 1:
The apparatus performs preliminary separation and concentration of samples with the same functional group in a single step before detection. The addition unit and flow paths are designed to pre-concentrate and separate samples based on their functional groups, eliminating the need for subsequent complex HPLC separation and reduction reaction steps
Solution Approach 2:
The invention extracts and isolates the essential function of separation and concentration into a dedicated preliminary step, removing unnecessary intermediate processes. By taking out the separation function from the complex HPLC workflow and implementing it as a standalone preliminary action, the system achieves both separation and detection without requiring multiple operation steps
