Component Separation TRIZ Cases
- Zero-Dead-Volume Tubing Fitting With Over-Compression Control
A primary seal and retaining member limit tubing over-compression while keeping a leak-tight, zero-dead-volume connection under high pressure.
- High-Pressure Seal Connector With Press-Fit Low Dead Volume
A spike-to-passageway press fit creates a high-pressure fluid seal with low dead volume, enabling precise robotic connection without twisting.
- Binary Pump Switching Valve for Backflow-Free Gradient Delivery
A three-state switching valve pre-pressurizes binary pump flow paths to prevent solvent backflow and keep mobile-phase delivery stable.
- Flat-Face Fluidic Connection for Tool-Free High-Pressure Sealing
A flat-face tube tip seals directly in a port, removing ferrules and tools while maintaining reliable high-pressure connections up to 25,000 psi.
- Capillary Tube Sealing Plug for Low-Dead-Volume HPLC Connections
An elastic sealing plug with axial compression aligns thin capillary tubes, cuts dead volume, and avoids seal detachment in HPLC connections.
- Biocompatible Chromatography Tubing With Leak-Proof High-Pressure Fittings
A polymer-lined metal tube and tapered ferrule fitting prevent sample contamination while maintaining leak-proof liquid chromatography at high pressure.
- Parallel Chromatography Column Assembly With Uniform Flow Paths
Integrated flow paths in a rigid housing equalize residence time across parallel chromatography modules while cutting manifold complexity, space, and cost.
- Multi-Piece Flow-Through Connector With Ceramic Flow Path
A ceramic flow path paired with a machinable non-ceramic body cuts connector cost and complexity while preserving inert, low-dead-volume flow.
- GC Detector Digital Subtraction for Low-Noise TCD Measurement
Digital subtraction replaces analog integrator and difference stages in TCD GC detection to improve SNR, reduce drift, and cut cost.
- GC Detector Digital Sigma-Delta Circuit for Low-Noise Measurement
Digital logic replaces the analog integrator in GC detection to cut power use, share counters across channels, and preserve SNR.
- Conductivity Detector Phase Alignment Across Switched Gain Ranges
Pre-set phase correction for each amplifier gain keeps conductivity waveforms continuous while extending measurement range and sensitivity.
