Electron/Ion Optical Arrangements TRIZ Cases
- Variable-Multipole Ion Guide for Ion Acceptance and Beam Focusing
A varying RF multipole field and tapered electrode ratio increase ion acceptance at entry while tightening beam focus and transfer through narrow apertures.
- Outer Source Lens Assembly With Keyed Contacts for Fast Reassembly
Keyed protrusions and socketed contacts keep mass spectrometer lens elements aligned during cleaning and reassembly, reducing errors and downtime.
- Flexible Ion Transfer Path for Low-Loss Mass Spectrometry
A flexible vacuum ion path with differential pumping and ion guides extends sampling distance while minimizing ion loss in mass spectrometry.
- FT Quadrupole Calibration Using Mathieu q and Secular Frequency
Secular frequency measurements at multiple RF voltages build a Mathieu q calibration curve for more accurate FT quadrupole m/z determination.
- Gradual Ion Transport Channel for Stable Mass Spectrometry Detection
A tapered ion transport channel strengthens the electric field, limits residue buildup, and improves mass spectrometry sensitivity and resolution.
- Multipole Ion Focusing Through a Low-Barrier Central Aperture
Symmetrical out-of-phase RF electrodes cut pseudopotential barriers, improving ion transmittance and beam coupling through a small aperture.
