Liquid Sample Receiving Line Continuity Detection for Remote Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample introduction systems for ICP spectrometry struggle to determine whether a sample transmitted through a transfer line from a remote sampling system contains a suitable continuous liquid segment for analysis, particularly over long distances, which can lead to inaccuracies and inefficiencies.
Innovation Solution
A system comprising a sample receiving line with first and second detectors configured to detect the presence of a liquid segment at different locations, and a controller that registers a continuous liquid segment when both detectors match detection states, ensuring that only a continuous sample is sent to the analysis system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sample transmission over long distances is implemented, then remote sampling capability is improved, but sample continuity verification becomes difficult
Solution Approach 1:
The patent introduces detectors as intermediary devices positioned at strategic locations along the transfer line to verify sample continuity. These detectors act as mediators between the remote sampling system and the analysis system, providing continuous monitoring and verification of liquid sample presence during transmission over long distances.
Solution Approach 2:
The system implements feedback control by using detectors to continuously monitor sample presence and providing real-time information to the control system. This feedback mechanism enables the system to verify sample continuity and make appropriate control decisions to ensure only continuous liquid samples are analyzed.
2Measurement precision
If multiple detectors are added to verify sample continuity, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent divides the transfer line into multiple monitoring zones by placing detectors at different locations. Each detector is responsible for verifying sample presence in its specific zone, and the control system integrates information from all zones to determine overall sample continuity. This segmentation approach improves verification accuracy while keeping each detector's function simple and well-defined.
