Chromatograph Data Processing Device for Joint Chromatogram Creation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data-processing devices for chromatographs create separate data files for each analysis, making it difficult to ensure temporal continuity and detect abnormalities or falsifications in chromatogram data obtained from different analyzing systems used for the same sample, as each analysis is treated as a new event.
Innovation Solution
A data-processing device that allows for the creation of a joint chromatogram from data collected during multiple analyses scheduled for the same sample, using a schedule table to manage analysis conditions and automatically switch between columns, enabling continuous data collection and display of chromatograms, with features to correct retention times for comparison across analyses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate data files are created for each analysis, then data organization for different analyzing systems is simplified, but temporal continuity and authenticity verification of chromatogram data become difficult
Solution Approach 1:
The patent merges multiple separate chromatogram data files into a single integrated data structure that preserves temporal continuity. The system combines chromatogram data from multiple analyses into one unified data file, allowing verification of temporal relationships between different analyzing systems while maintaining organized data storage.
Solution Approach 2:
The patent implements a nested data structure where individual chromatogram data files are embedded within a master data file. Each individual analysis data file contains its own chromatogram information, while the master file orchestrates these individual files with timing and sequence information, creating a hierarchical nesting that enables both detailed analysis and overall temporal verification.
2Adaptability or versatility
If multiple analyses are performed using different analyzing systems, then comprehensive analysis of sample components is achieved, but detection of abnormalities or falsifications becomes difficult
Solution Approach 1:
The patent implements feedback mechanisms that automatically compare chromatogram data across different analyzing systems and time points. The system monitors for abnormalities by analyzing patterns and deviations in the data, providing feedback that highlights potential falsifications or errors in real-time during the analysis process.
Solution Approach 2:
The patent performs preliminary verification of data authenticity by establishing baseline patterns from initial analyses before proceeding with subsequent analyses. This preliminary action creates reference data that is used to detect abnormalities in later analyses, enabling early identification of potential issues.
3Ease of manufacture
If conventional data processing creates separate files for each injection, then data storage is simplified, but efficient analysis of multiple components across different systems is hindered
Solution Approach 1:
The patent creates a universal data structure that serves multiple functions simultaneously: it stores individual chromatogram data, maintains temporal sequences, enables cross-system comparison, and supports various analysis methods. This multi-functional data structure eliminates the need for separate processing approaches for different analyzing systems.
Solution Approach 2:
The patent introduces an intermediary data processing layer that translates and harmonizes data from different analyzing systems into a unified format. This intermediary structure enables efficient analysis across multiple components and systems while maintaining the simplicity of storage through standardized data organization.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures temporal continuity and sameness of chromatograms, facilitating easy detection of abnormalities or falsifications, and allowing for efficient analysis of multiple components in a single data set, enhancing the validity and authenticity verification of analysis results.
Implementation Method 1
The components in the sample are thereby separated from each other due to their difference in the interaction with the stationary phase (which may also be called a 'packing material') and the mobile phase in the column
