Liquid Sample Transfer Detection for Gap-Free Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in determining whether a sample transmitted through a remote sampling system contains a suitable amount of liquid for analysis by an analysis system, particularly in long-distance transfers, where gaps or voids can form in the sample transfer line, compromising analysis accuracy.
Innovation Solution
A system with detectors at multiple locations along the sample receiving line, including a first and second detector, and a controller to register a continuous liquid segment by matching detection states, ensuring a sufficient sample is present before allowing transfer to the analysis device, thereby avoiding gaps or voids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If long-distance sample transfer is implemented, then sampling versatility is improved, but gaps or voids may form in the transfer line compromising measurement precision
Solution Approach 1:
The system performs preliminary detection of liquid presence at multiple locations along the transfer line before analysis begins. Detectors positioned at different points detect liquid presence ahead of time, allowing the system to verify continuous liquid flow is established before initiating the analysis sequence, thus preventing gaps from compromising measurement precision
Solution Approach 2:
The system uses feedback from multiple detectors positioned along the transfer line to continuously monitor liquid presence. The controllers receive signals from these detectors and use this feedback information to determine whether continuous liquid flow is maintained throughout the transfer line, allowing real-time verification that prevents analysis of gapped samples
2Measurement precision
If multiple detectors are positioned along the sample receiving line, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The transfer line is segmented into multiple detection zones with detectors positioned at different locations. Each detector monitors a specific segment of the liquid flow, allowing the system to verify continuous liquid presence throughout the entire transfer line through coordinated detection at multiple points rather than requiring a single complex detector
Solution Approach 2:
Multiple detectors are used to perform multiple functions: detecting liquid presence at different locations, verifying continuous flow, and providing spatial information about liquid segment position. This multi-functional approach uses simple detector components to achieve complex verification goals that would otherwise require sophisticated single-component systems

AI summary
Systems and methods are described to determine whether a sample transmitted through a transfer line from a remote sampling system contains a suitable sample to analyze by an analysis system. A system embodiment includes, but is not limited to, a sample receiving line configured to receive a liquid segment a first detector configured to detect the liquid segment at a first location in the sample receiving line; a second detector configured to detect the liquid segment at a second location in the sample receiving line downstream from the first location; and a controller configured to register a continuous liquid segment in the sample receiving line when the first detector and the second detector match detection states prior to the controller registering a change of state of the first detector.
