Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing sample targets with porous alumina layers, liquid samples can spread from one region to another during ionization, leading to incomplete analysis and contamination between measurement regions.
Innovation Solution
A sample support body with a substrate and a porous layer featuring partition grooves that separate regions, where the grooves are wider than they are deep, preventing sample spread and allowing for efficient ionization and mass spectrometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a porous alumina layer is used for sample ionization, then ionization efficiency is improved, but sample spread between regions occurs
Solution Approach 1:
The front surface of the porous layer is divided into multiple independent measurement regions by forming partition grooves. These grooves physically separate the regions, preventing liquid samples from spreading between them while maintaining the ionization functionality of the porous alumina material in each region.
Solution Approach 2:
Different regions on the front surface are given distinct functions through partitioning. Each measurement region can be optimized for specific ionization tasks, and the partition grooves create local boundaries that control sample flow patterns, ensuring samples remain confined to their designated regions.
2Productivity
If multiple measurement regions are created for simultaneous analysis, then productivity is improved, but sample contamination between regions increases
Solution Approach 1:
The front surface is segmented into multiple measurement regions that can simultaneously accommodate different liquid samples. The partition grooves ensure complete isolation between regions, allowing parallel analysis of multiple samples without cross-contamination, thereby increasing productivity while maintaining precision.
3Manufacturing precision
If partition grooves are formed to prevent sample spread, then region isolation is improved, but device complexity increases
Solution Approach 1:
The partition grooves are formed within the porous alumina layer, utilizing the material's inherent porous structure. This approach integrates the partitioning function into the existing porous layer without requiring additional complex structures, maintaining simplicity while achieving effective region isolation.
