Chromatogram Synthesis for Non-Composition Substance Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity in identifying peak components in gasoline chromatograms is heightened by the large number of substances and the presence of non-composition substances in samples, making it difficult to distinguish between composition and non-composition substances using traditional PONA analysis methods.
Innovation Solution
An analytical data analysis system that compares standard and analysis target chromatograms, synthesizing non-composition substance information with the standard chromatogram to display peak expression positions and identification information, facilitating visual comparison and identification of both composition and non-composition substances.

Engineering Contradiction Analysis
1Measurement precision
If traditional PONA analysis methods are used to identify peak components, then composition substances can be identified by comparison with standard samples, but the identification work becomes extremely complicated when non-composition substances are present
Solution Approach 1:
The chromatogram information is segmented into two distinct parts: standard chromatogram data (containing only composition substances) and non-composition substance information (containing additives and other non-composition substances). This segmentation allows the system to handle different types of substances separately, reducing identification complexity while maintaining accuracy.
Solution Approach 2:
The system performs preliminary action by pre-acquiring and storing non-composition substance information (such as additive data) in advance. When analyzing a sample, this pre-stored information is automatically integrated with the standard chromatogram, so that non-composition substances are already accounted for before the actual identification process begins, simplifying the workflow.
2Adaptability or versatility
If non-composition substances are included in the analysis, then complete substance identification is achieved, but the peak expression positions overlap and confuse the identification process
Solution Approach 1:
The system applies local quality by displaying non-composition substance information at specific local positions on the chromatogram (such as alongside or near the corresponding peak positions). This localized presentation allows users to easily associate non-composition substances with their respective peaks without confusion from overlapping information across the entire chromatogram.
Solution Approach 2:
The system introduces an intermediary element (the integrated chromatogram display that combines standard chromatogram and non-composition substance information) that mediates between the raw chromatogram data and the final identification result. This intermediary presentation layer organizes and contextualizes the information, making it easier to differentiate between composition and non-composition substances.

AI summary
An analytical data analysis system (2) is a system that identifies composition substances contained in the sample to be analyzed and non-composition substances that are not the composition substance contained in the sample to be analyzed by comparing a standard chromatogram and an analysis target chromatogram. The analytical data analysis system (2) includes a non-composition substance information holding part (12) holding identification information and information on a peak expression position on a chromatogram of substances that may exist as the non-composition substance, a chromatogram synthesis part (16) configured to synthesize the information held in the non-composition substance information holding part with the standard chromatogram in order to describe identification information and the peak expression position of the substances that may exist as the non-composition substance on the standard chromatogram in which the composition substances of the standard sample are described, and a chromatogram display part (18) configured to display the analysis target chromatogram together with the standard chromatogram synthesized by the chromatogram synthesis part (16) on the display device (6).
