Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If plasma is used for atomization, then atomization efficiency and ionization efficiency are improved, but background signal increases and detection limits worsen
Solution Approach 1:
The device divides the plasma generation into two separate chambers: a first chamber where plasma is generated at high power, and a second chamber where atomization and detection occur. This segmentation allows the plasma to be generated with high energy while the detection region maintains low background signal, resolving the contradiction between atomization efficiency and background signal levels.
2Measurement precision
If higher power is used in plasma, then detection limits for hard-to-ionize species are improved, but background signal increases
Solution Approach 1:
By separating plasma generation from the detection zone into different chambers, the system can apply high power to the first chamber to achieve low detection limits for difficult-to-ionize species, while the second chamber maintains optimal conditions for detection with minimal background interference.
Solution Approach 2:
The first chamber acts as an intermediary that performs the high-energy plasma generation function, allowing the second chamber to focus on detection without the harmful background signal. The plasma-generated species are transported to the second chamber where detection occurs with reduced background interference.
3Productivity
If liquid sample is injected into plasma, then atomization is enhanced, but plasma temperature decreases due to evaporation
Solution Approach 1:
The device separates the sample introduction and initial vaporization function from the main plasma generation zone. The liquid sample is introduced and vaporized in a region separate from the high-power plasma, preventing the evaporative cooling effect from significantly reducing plasma temperature while still achieving effective atomization.
