Analysis Using Chemical Indicators TRIZ Cases
- Retractable Sheath Sample Probe for Sealed Powder Screening
A retractable sheath and needle collect particulate samples through sealed containers for rapid screening while limiting exposure and preserving evidence.
- Photonic Colorimetric Sensor Using MIP Layers for Visible Analyte Detection
Lamellar photonic polymers with molecularly imprinted layers create immediate visible color shifts for discreet analyte detection in fluids.
- Container and Preform Treatment Chamber with Dual-Range Sensing
A dual-range sensing layout isolates the low-concentration sensor from sterilant peaks, enabling faster accurate readings after sterilization.
- Dye-Mediated Optical Colloid Charge Measurement for Flocculant Dosing
A dye-mediated optical reading and calibration curve replace costly zeta-potential measurements and complex titration for flocculant requirements.
- Conjugated Polymer Structural Color Films for Chemical Sensing
Chemical doping tunes refractive index in conjugated polymer films, avoiding expensive lithography while enabling multicolor chemical sensing.
- Sequential Colorimetric Measurement of Zinc and Copper in Aqueous Samples
Sodium ascorbate reduction and sequential BCA–Zincon chelation measure copper and zinc in aqueous samples with reduced interference.
