Solution Overview
Problem
Existing methods for detecting whether a substance is present in a sample require manual analysis of multiple derived substances, which is time-consuming and inefficient, particularly for polymers with high molecular weights that are difficult to dissolve.
Innovation Solution
An analysis data processing device and method that associates first substances with their decomposition or reaction products, using Pyrolysis-Gas Chromatograph-mass Spectrometer (Py-GC-MC) to separate and detect components, and an information processor to determine the presence of first substances based on detection data and substance databases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual analysis of multiple derived substances is performed to determine presence of a substance, then detection accuracy is improved, but analysis time and effort increase
Solution Approach 1:
The system performs preliminary actions by pre-storing substance data including decomposition and reaction products in a database before analysis. During actual analysis, the information producer automatically retrieves and compares detected substances against this pre-prepared data, eliminating the need for manual case-by-case examination while maintaining accurate detection of the target substance through its decomposition products.
Solution Approach 2:
The information producer automatically determines the presence of the target substance by self-comparing detected substances against stored substance data without requiring external manual analysis. The system serves itself by autonomously processing detection results, identifying decomposition products, and concluding substance presence based on predefined criteria, thereby reducing dependency on analyst time and effort.
2Reliability
If detection of multiple derived substances is performed to identify a polymer, then detection reliability is improved, but device complexity increases
Solution Approach 1:
The information producer serves multiple functions: it detects decomposition products, identifies reaction products, determines target substance presence, and generates comprehensive analysis results. This multi-functional approach consolidates what would otherwise require multiple separate analytical systems into a single integrated device, maintaining high detection reliability through comprehensive substance identification while reducing overall system complexity.
Solution Approach 2:
The substance data stored in the database acts as an intermediary between the detection system and the analysis conclusion. It contains pre-defined relationships between target substances and their decomposition/products, serving as a reference mediator that translates complex detection data into reliable substance identification without requiring complex real-time analysis algorithms.
3Productivity
If automated analysis processing is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-storing comprehensive substance data including decomposition pathways and reaction products in a database before automated analysis. During operation, the information producer automatically retrieves and compares detected substances against this pre-prepared reference data, enabling rapid automated determination of target substance presence without complex real-time computational algorithms, thus improving productivity while keeping the processing system relatively simple.
Solution Approach 2:
The system uses stored substance data as a reference copy or template for comparison against actual detection results. The information producer copies expected decomposition product patterns from the database and compares them with detected substances, enabling automated analysis through simple pattern matching rather than complex computational processing, thereby improving productivity without significantly increasing device complexity.
