Samples Introduction/Extraction TRIZ Cases
- Membrane Purge Gas Transfer for Stable Laser Ablation ICP Analysis
A gas exchange membrane replaces atmospheric gases with sweep gas during laser ablation transfer, keeping the ICP torch stable without pinch valves.
- Complemented Ion Funnel Layout for Low-Fragmentation Ion Transfer
Offset gas exhaust, staged electrodes, and DC/RF guidance improve ion transfer into vacuum while reducing turbulence and fragmentation.
- Imaging Mass Spectrometry Stage Motion for Vibration Control
Intermittent 2D stage motion suppresses vibration at measurement points, preserving spatial resolution while speeding imaging mass spectrometry.
- Shaped-Channel Scanning Nozzle for Single-Chamber Wafer Analysis
Shaped fluid channels and vacuum recovery enable single-chamber wafer decomposition and scanning with less handling, contamination risk, and footprint.
- MALDI Matrix Transfer for Precise Multi-Matrix Sample Preparation
Laser ablation transfers multiple MALDI matrices to preset sample positions, improving crystal uniformity, sensitivity, and reproducibility.
- Dual-Outlet Sample Chamber for Sensitive Laser Ablation Analysis
A dual-outlet flow chamber separates high washout flow from low analysis flow, enabling depth-resolved laser ablation with mass spectrometry.
- Mass Spectrometer Beam Focusing Correction for Temperature Drift
Temperature-based position correction keeps the excitation beam focused on the sample, preserving spatial resolution and ionization efficiency.
- Dual-Path Detector Inlet for Aerosol Vaporization and Low Power
Separate vapor and aerosol pathways let the heater run only for aerosol sampling, improving detector sensitivity while limiting power use and contamination.
- Swab-Based Ionized Sample Introduction for Non-Volatile Detection
A charged solvent-wetted swab forms a Taylor cone spray that delivers non-volatile trace chemicals into IMS or MS without thermal decomposition.
- Through-Hole Sample Support for High-Sensitivity Mass Spectrometry
Derivatizing agent placed in through holes boosts ionization signal intensity while preserving position information and spatial resolution in mass spectrometry.
- Systems and methods for quantifying an analyte extracted from a sample
A capillary extraction approach circulates immiscible fluids to isolate and pre-concentrate analytes, suppressing matrix effects before MS analysis.
- Intermediate Aerosol Chamber for Stable Mass Spectrometry Sampling
An intermediate chamber decouples plume collection from injection, reducing aerosol variability and improving mass spectra stability and signal-to-noise.
- Pyrohydrolysis ICP-MS Halogen Detection Without Deflagration
Staged pyrohydrolysis with asbestos covering and online ICP-MS enables rapid, accurate Cl, Br, and I detection while avoiding deflagration.
- Ion Mobility Mass Analysis for Fast Isomer Interference Separation
Timed ion mobility control separates isomeric and isobaric interferences while preserving high-throughput mass analysis speed.
