Analyzer Calibration Timing Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional analyzers perform calibration and blank analysis processes simultaneously, leading to high costs when calibrators are expensive, as users demand the ability to perform these processes separately to avoid unnecessary expenses.
Innovation Solution
The analyzer independently manages the initiation timings of calibration and blank analysis processes, allowing them to be performed only when necessary, ensuring accuracy and reducing costs by scheduling them based on reagent supply and expiration dates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the calibration analysis process and blank analysis process are performed simultaneously, then the analysis accuracy is maintained, but the cost increases due to frequent calibration analysis
Solution Approach 1:
The patent segments the calibration analysis process and blank analysis process into independent, separately manageable processes. The calibration analysis process sets the calibration curve while the blank analysis process corrects it. By managing their initiation timings independently, the system performs calibration analysis only when the calibration curve needs updating (when reagent is supplied or calibration validity period expires), rather than simultaneously with every blank analysis, thereby reducing unnecessary calibration costs while maintaining accuracy through separate blank corrections.
2Measurement precision
If the calibration analysis process is performed frequently to maintain accuracy, then the analysis accuracy is maintained, but the resource consumption increases
Solution Approach 1:
The patent implements preliminary action by establishing calibration validity periods and tracking reagent supply events in advance. The system determines beforehand when calibration analysis is actually needed (when calibration curve validity expires or new reagent is supplied) versus when only blank analysis is needed. This preliminary planning prevents unnecessary calibration analysis and associated reagent consumption while ensuring calibration accuracy is maintained through timely calibration when required.
3Loss of substance
If the calibration analysis process and blank analysis process are managed independently, then the cost is reduced, but the system complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where the control unit continuously monitors calibration validity periods, tracks reagent supply events, and receives feedback from both calibration analysis and blank analysis processes. Based on this feedback, the system intelligently determines whether to initiate calibration analysis, blank analysis, or neither, by comparing current state against predefined conditions (calibration validity expiration, reagent supply timing). This feedback-driven approach manages the complexity of independent process control while enabling cost reduction through optimized process initiation.

AI summary
An analyzer (1) according to the present invention maintains its analysis accuracy for each analytical item by performing a calibration analysis process, in which a calibrator is analyzed, and a blank analysis process, in which a blank sample is used. The analyzer (1) includes a management unit (32) that independently manages the initiation timings of the calibration analysis process and the blank analysis process for each analytical item. The management unit (32) performs at least the blank analysis process before an expiration date for managing accuracy of the blank analysis result and when a reagent is supplied. The management unit (32) performs the calibration analysis process before the expiration date for managing accuracy of the calibration analysis result and when a reagent is supplied.
