Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chromatograph control devices are cumbersome in managing analysis conditions and results when handling both liquid chromatograph and supercritical fluid chromatograph functions, as they require separate batch files for each type, limiting the ability to perform continuous, exhaustive analyses of various compounds.
Innovation Solution
A control device that creates a single batch file combining method files for liquid chromatograph and supercritical fluid chromatograph analyses, with features like distinct display modes and automatic switching method file creation to manage and execute both types of analyses seamlessly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate batch files are used for liquid chromatograph and supercritical fluid chromatograph analyses, then each analysis type can be managed independently, but the management of analysis conditions and results becomes cumbersome and complex
Solution Approach 1:
The patent merges the management of LC and SFC analysis conditions and results into a single batch file. The control device creates a unified batch file that can contain both LC method files and SFC method files, allowing both analysis types to be managed together in one consolidated structure, thereby reducing the complexity of file management while maintaining the ability to perform both analysis types
Solution Approach 2:
The batch file structure is designed to be universal, capable of accommodating both liquid chromatograph and supercritical fluid chromatograph method files. This multi-functional batch file can store and execute different types of analysis methods within a single file, eliminating the need for separate batch files for each analysis type and simplifying the overall system operation
2Productivity
If separate batch files are used for LC and SFC analyses, then each analysis can be executed independently, but continuous exhaustive analysis of various compounds becomes difficult
Solution Approach 1:
By combining LC and SFC method files into a single batch file, the system enables continuous exhaustive analysis of various compounds. The unified batch file structure allows sequential execution of both LC and SFC analyses without requiring switching between separate files, thereby improving productivity and making it easier to manage analysis conditions and results throughout the continuous analysis process
3Adaptability or versatility
If conventional control devices are used for LC-SFC apparatus, then compatibility with existing systems is maintained, but the ability to seamlessly integrate and execute both analysis types in one batch sequence is limited
Solution Approach 1:
The control device employs a universal batch file creation mechanism that can accommodate both LC and SFC method files. This unified approach allows the system to seamlessly integrate both analysis types into a single batch sequence, making it easier to create and manage batch files while maintaining compatibility with existing control device functionalities
