Chromatograph Data Processor Automates Batch File Creation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face a significant burden in creating batch files for chromatograph analysis, as they need to manually input and manage various sample analysis conditions and preparation details for each sample, which is time-consuming and prone to errors.
Innovation Solution
A chromatograph data processor and automatic sample injector system that assigns analysis information to jigs corresponding to sample holders, using detectors to identify samples and jigs, and automatically creates batch files based on acquired information, reducing user input and error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually create batch files by inputting analysis conditions and sample information, then the batch file can be created with complete information, but the user burden and time consumption increase significantly
Solution Approach 1:
The system enables self-service batch file creation by automatically acquiring sample holder information and jig information through detectors, and generating the batch file without requiring manual user input. The chromatograph data processor autonomously collects data from detectors and creates the batch file based on acquired information.
Solution Approach 2:
Analysis information is pre-assigned to different kinds of jigs before the analysis process. The system detects which jig is attached to which sample holder, and automatically retrieves the corresponding pre-assigned analysis information, eliminating the need for users to input conditions during batch file creation.
2Loss of information
If users manually input sample analysis conditions and preparation details, then complete analysis information can be obtained, but the process becomes complex and error-prone
Solution Approach 1:
The system automatically collects all necessary analysis information through detectors that read sample holder and jig identifiers. The chromatograph data processor autonomously retrieves pre-assigned analysis conditions based on detected jig information, eliminating manual information gathering and reducing complexity.
Solution Approach 2:
Jigs serve as intermediaries that link sample holders with their corresponding analysis conditions. Each jig carries identification information that enables the system to automatically retrieve the correct pre-assigned analysis information, simplifying the information flow without manual intervention.
3Productivity
If the system automatically detects sample holders and jigs, then batch file creation is simplified and speeded up, but detection accuracy requirements increase
Solution Approach 1:
Jigs act as detectable intermediaries between sample holders and the detection system. The detectors read identification information from jigs, which then links to the corresponding sample holder and its analysis conditions. This intermediary approach enables reliable automatic detection while maintaining system flexibility.
Solution Approach 2:
The system uses feedback from detectors to identify which jig is attached to which sample holder, then retrieves the corresponding pre-assigned analysis information. This feedback loop ensures accurate matching of samples with their analysis conditions, maintaining detection accuracy while enabling automation.

AI summary
First analysis information including at least one of a sample analysis condition, a sample preparation condition and a kind of sample is assigned to at least one kind of jig, and the jig is arrangeable to correspond to any of a plurality of sample holders. Holding information representing whether a sample is held by each sample holder and jig information for identifying the kind of jig are acquired by a first information acquirer from an automatic sample injector. The first analysis information in regard to a corresponding sample holder is specified by a first analysis information specifier based on jig information. A batch file for controlling a sequence of analysis or preparation in regard to a sample held by a sample holder corresponding to a jig is created by a batch file creator with use of the holding information and the first analysis information.
