Analysis Using Chemical Indicators TRIZ Cases

Applying a predetermined chemical generates a reference signal that compensates for substrate density and material degradation in colorimetric gas detectors.

Optical blood oxygen sensor differentiates arterial from venous samples to prevent accidental cannulation during emergency central line placement.

This system replaces manual inspection with visual feedback from a composite ink that changes color upon contact with diverse sorbates, reducing labor costs.

Online FTIR analysis detects PMIDA concentration to adjust oxygen flow and temperature, reducing by-product formation while maintaining high yield.

Segmented lid design allows simultaneous probe and evacuated tube sampling without removal, reducing contamination risk and processing time.

Selective fluid access prevents cross-contamination in high-density arrays while minimizing dead volume during precise sample loading.

A BODIPY derivative compound enables rapid fluorescent detection of oil pH and viscosity changes.

Grooves on the enlarged bottom surface of a polypropylene pipette tip block capillary wicking, ensuring precise volumetric dispensing for veterinary analyzers.

Replaceable testing material impregnated with o-tolidine detects nitric oxide through color change.

Compatible solute ectoine preserves dehydrogenase activity within a solvent-free dry composition for diagnostic applications.

Cooled air circulates through the reagent case to maintain uniform temperature and reduce evaporation.

A multisensor array uses chemo-selective compounds to detect gas phase analytes through physicochemical property changes.

A color-changing indicator replicates substrate shape to visualize plasma treatment distribution directly.
