Spectrometer Circuit Arrangements TRIZ Cases
- Bench-Top TOF Mass Spectrometer With Auto Module Configuration
Automatic module detection and remote configuration make bench-top TOF mass spectrometry easier to start, customize, and use.
- Ion Trap RF Tuning for Broad Mass-Range Detection
Adjustable RF amplitude and frequency in an ion trap expand mass-range detection while improving sensitivity and limiting interference currents.
- Electrostatic Linear Ion Trap With Offset Trajectories for Multi-Ion CDMS
Offset planar or nested cylindrical ion paths let one ELIT measure multiple ions simultaneously, reducing CDMS analysis time while preserving accuracy.
- Mass Spectrometer Feed-Through Connector for Wire-Free Lens Assembly
Biasing contact terminals replace lens wiring in a mass spectrometer, simplifying attachment, detachment, and maintenance.
- Switchable Ion Guide for Interference-Free Isotope Ratio Analysis
A switchable collision cell uses RF focusing when pressurized and static focusing when evacuated to cut noding effects and interferences.
- RF Travelling-Wave Ion Sorting for Low-Loss m/z Separation
Combining RF travelling waves with opposing DC fields spatially sorts ions by m/z, reducing ion wastage in mass spectrometry.
- Leak-Detection Mass Spectrometer With Dual-Sensitivity Field Tuning
Dual-sensitivity magnetic field adjustment helps leak-detection mass spectrometers handle tracer-gas changes and environmental disruption with better precision.
- Mass Filter Wave Detection With Parallel Rectifiers and Offset Cancellation
Parallel rectifiers and offset cancellation improve wave-detection linearity, reducing mass deviation across wide mass-to-charge ranges.
- Balanced Transformer Drive for Low-Noise High-Voltage Switching
A balanced high-frequency drive and symmetric stray-capacitance transformer suppress common-mode noise while keeping polarity inversion fast.
- Floated HV Supply Shielding for Low-Noise Ion Detector Bias
Resistive return-path isolation and floating/Faraday shields cut bias-supply noise coupling, reducing ripple in mass spectrometer ion detectors.
- Trapped Ion Mobility Filter With Differential Ion Trapping
Alternating axial fields and a counteracting force trap selected ions by differential mobility while transmitting others for complex sample analysis.
- Hydrophobic Thread Electrospray for Direct Microsample Analysis
A hydrophobic thread stabilizes tiny biological samples and enables direct electrospray mass spectrometry without dilution or extensive prep.
- PCB Ion Funnel Structure With Guard Rails and Gas Venting
Triangular PCB faces, guard rails, and vent slots improve ion transmission, reduce edge losses, and ease high-volume ion funnel assembly.
- 2D Ion Mobility Filtering for Continuous Ion Separation
A 2D ion filter uses electrode arrays and counterflow gas to continuously separate narrow mobility ranges while reducing ion loss.
- Gaussian Fitting for Real-Time TOF Mass Spectrometry Signals
Gaussian fitting processes digitized TOF ion signals in real time to improve arrival-time precision, signal intensity accuracy, and high-rate throughput.
- Electrostatic Linear Ion Trap Array for Parallel Ion Charge Measurement
Parallel ELIT regions let ions oscillate through separate charge detection cylinders, raising measurement rate without sacrificing precision.
- MR-ToF Voltage Supply Circuit for Fast Polarity Switching
Bridge-switched HV regulators let MR-ToF mass spectrometers change polarity faster with fewer supplies, cutting settling time and circuit complexity.
