Ion Sources/Guns TRIZ Cases
- PET Fiber MALDI-MS Pretreatment for Recycled Fiber Discrimination
THF pretreatment separates PET oligomers before MALDI-MS, improving recycled fiber discrimination accuracy without slow chromatography.
- Ion Source Gas Filtration and Flow Control for Biohazard Containment
Filtered gas flow and flow-rate feedback keep sprayed biohazard samples contained inside the ion source and safely vented.
- Nebulizer Electrode Tip Positioning by Pressure Drop Detection
Pressure-drop sensing sets the nebulizer electrode tip at the optimal nozzle position, improving mass spectrometry sensitivity and reproducibility.
- Spring-Biased Sprayer Sheath for Capillary Protection and Alignment
A movable spring-biased sheath protects the fragile DESI capillary outlet while preserving nozzle alignment and reproducible spray quality.
- Split-Ring Resonator Ion Source With Stable RF Impedance Matching
Multiple RF input points and an offset source electrode keep impedance matched before and after plasma ignition while improving ion extraction.
- Chemical Fluid Filtration for Trace Metal Control in Semiconductor Patterning
Multistage filtration and Single Particle ICP-MASS cut Fe, Cu, and Zn particulates to support ultrafine semiconductor pattern quality.
- Mass Spectrometry Imaging with Region-Path MS/MS Identification
Region-based path selection adds targeted DESI MS/MS to MSI data, improving molecular identification without analyzing every pixel.
- Rutile-Based Hydrothermal Fluid Path Mapping in Porphyry Copper
Rutile zirconium and titanium isotope data map ore-forming hydrothermal fluid paths in porphyry copper deposits with higher accuracy and less exploration time.
