Spectrometer Circuit Arrangements TRIZ Cases
- Quadrupole Pre-Rod Biasing for Higher Ion Transmission
Adding DC bias to quadrupole pre-rod electrodes improves ion transfer into the main rod section and raises mass spectrometer sensitivity.
- Charge Detector Calibration for ELIT Gain Drift Compensation
High-frequency charge injection and ion oscillation compensate ELIT detector drift, improving low-signal charge and m/z measurement accuracy.
- Linear Ion Trap Activation Using Pulsed Gas Discharge Beams
Pulsed gas discharge injects dense charged particles into a linear ion trap for precise ion activation and dissociation without degrading vacuum conditions.
- Ion Guide Breakdown Detection and RF Control
Light or particle detection triggers RF voltage and gas control to prevent electrical breakdown and ion contamination in large ion guides.
- Linear Ion Trap Trigger Thresholds for Weak Ion Capture
Dynamic trigger thresholds let an electrostatic linear ion trap capture weakly charged ions despite detector noise, improving trapping and measurement.
- Wireless High-Voltage Isolation in Portable Mass Spectrometry
RF links replace bulky opto-isolators between separate high-voltage ground planes, improving safety, size, and reliability in portable mass spectrometers.
- Y-Directional Ion Trap Control for High-Pressure Mass Spectrometry
Supplemental y-axis electric fields steer ions to a single ejection point, preserving resolution and signal intensity at higher trap pressures.
- Ion Mobility Peak Compression Using Intermittent Traveling Waves
Intermittent traveling waves refocus broadened ion packets into narrower peaks, improving ion mobility resolution and signal-to-noise ratio.
- Ion Detection Amplifier Compensation With Remote High-Voltage Tuning
Voltage reduction and neutralizing amplification let digital resistors remotely tune ion detector compensation without losing high-voltage accuracy.
