Chromatography Column Usage Information Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing usage information storage devices attached to analytical columns in chromatography systems are prone to damage due to high temperature conditions, leading to a loss of usage information and inadequate management of the analytical columns.
Innovation Solution
A chromatography system with a separate usage information holding part and managing part that keeps and updates usage information for each analytical column, allowing for proper management even if the primary storage device is damaged, including features for restoring usage information and notifying users of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a usage information storage device is attached to each analytical column, then usage information can be stored, but the storage device is damaged by high temperature conditions in the column oven
Solution Approach 1:
The patent creates a copy of the usage information storage function by implementing a usage information managing part in the chromatography system that stores usage information separately from the analytical column. This backup mechanism ensures that even if the primary storage device attached to the column is damaged by heat, the usage information remains preserved and can be retrieved from the system's memory.
2Ease of operation
If the usage information storage device is housed in the column oven with the analytical column, then the column can be managed, but the storage device is easily damaged by heat
Solution Approach 1:
The patent extracts the usage information storage function from the column oven environment by implementing a separate usage information managing part in the chromatography system. This allows the analytical column to remain in the heated column oven for proper operation while the usage information is stored and managed separately in a temperature-controlled environment, preventing heat damage to the storage device.
3Device complexity
If a single storage device is used for usage information, then the system is simple, but data loss occurs when the device is damaged
Solution Approach 1:
The patent implements beforehand cushioning by creating a backup storage mechanism for usage information. The usage information managing part continuously stores usage information in the chromatography system's memory, providing a safety cushion against potential damage to the primary storage device. This ensures that even if the storage device attached to the analytical column fails, the usage information is preserved and can be retrieved.

AI summary
Provided is a chromatography system including a usage information storage device, a column usage information holding part, and a usage information managing part. The usage information storage device is provided corresponding to the analytical column incorporated in the chromatography system and is configured to keep usage information for each corresponding analytical column. The column usage information holding part is provided separately from the analytical column and is configured to keep usage information for each of the analytical columns which may be incorporated in the chromatography system. The usage information managing part is configured to update, at a timing when an analysis process of separating a sample injected into the analysis channel using the analytical column is executed, the usage information kept by the usage information storage device and the usage information kept by the column usage information holding part in association with the analytical column to latest usage information.
