Samples Introduction/Extraction TRIZ Cases
- Dual Polarity Spark Ion Source for Trace Detection
A dual polarity spark ion source generates positive and negative ions using a high voltage fast switching circuit.
- Gas Phase Molecule-Ion Reaction Mass Spectrometer
A mass spectrometer with a reaction gas introduction device and quantitation mechanism reduces ion trap pollution while enhancing detection strength.
- Tilted RF Multipole Ion Guide for Mass Spectrometry Noise Reduction
A tilted RF multipole ion guide transports ions through vacuum stages while blocking background particles from reaching the detector.
- Gas Sampling Device Pressure Reduction for Condensation Control
A gas sampling device uses a calibrated expansion nozzle to lower pressure and reduce the dew point of sampled gases.
- GCB Membrane for SPE/SALDI-MS Pesticide Analysis
Graphitized carbon black membrane eliminates matrix ion interference during pesticide analysis by replacing organic acid matrices with adsorbent particles.
- Mass Spectrometer Aperture Electrode Angular Alignment
Eccentric angular alignment between aperture electrodes separates noise components from ions, maintaining high sensitivity without orthogonal ion loss.
- Mass Spectrometer Dynamic Exclusion for Peptide Analysis
A mass spectrometer system calculates ion valence and mass number to distinguish species during tandem analysis.
- Mass Spectrometer Ionization Chamber Pneumatic Cleaning
Pneumatic cleaning removes bacterial cell fragments from the mass spectrometer ionization chamber floor without disassembly.
