Analysis Using Chemical Indicators TRIZ Cases

Segmented treatment zones on the cover slip enable parallel cell staining, reducing reagent consumption and eliminating fluid leaks.

Cobinamide assays resolve throughput and sensitivity trade-offs in biological sample analysis.

Multiple sequential test sections on a continuous strip allow frequent liquid analysis, resolving the trade-off between testing frequency and system complexity.

A calcium test strip uses 8-hydroxyquinoline and OCPC reagents to detect calcium concentration in body fluids.

A specimen cup system with a rotatable base and dual-chamber design manages fluid communication between chambers.

A colorable gel composition detects substance penetration through packaging materials while maintaining its shape under heat treatment.

Filtration-based inspection module separates blood serum for rapid immunoglobulin concentration measurement using a portable FPW sensor.

Segments aqueous samples into droplets using an oil phase with embedded signaling molecules, enabling selective ion detection without optical interference.

Water stoppers prevent premature sample entry into common paths, ensuring consistent measurement accuracy despite manufacturing variations.

Linker molecules optimize dye-nanoparticle spacing to resolve weak SERRS signals and enable femto-molar detection limits.

Gravity-aligned indicator member rotates freely on a camera extension to show pipe orientation.
